From YouTube: Xamarin: .NET Community Standup - April 2nd 2020 - Tooling Updates with Pierce

Description

Join the Mobile .NET Teams for our community standup covering great community contributions for Mobile .NET, Xamarin, Xamarin.Forms, Components, and more.

Community Links: https://www.theurlist.com/xamarin-standup-apr2020

Suggest an idea for a standup: http://aka.ms/dotnet-standup-suggestion.

A

You I programmed it correct. We did it: hey, hey, alright, welcome everyone to the dotnet community, stand up, xamarin edition, remotes hashtag stay at home. Don't leave your solution right here. Oh my goodness, and we're figuring out here that both Madi and peers have I think they both have breo's and it's like following them. So if anyone in the chat knows how to turn off the auto follow mode, please let us know: hey everyone in the chat.

A

We have a lot of people a lot of people on the xamarin YouTube on the twitch on the mixers on the Donna foundation. Welcome everyone we're we're monitoring the chat, lots of good emotes and hellos from all over the world, which is awesome. Hopefully a lot of people got to join us last week on the.net compos Ameren edition, which is super duper awesome, which was super fun to do again. Now it was at nine hours. The content is crazy.

A

Super cool we're keeping the dotnet stand-ups going the asp.net ones going every Tuesday. Of course we do on the first of every first Thursday of every month. So it's a second. It's a bunny day, bunny days are happening in our Animal Crossing worlds. I, don't know if Pierce's planning.

B

C

A

Right kick him off the stream now I, don't.

C

Turn ups today.

A

Only 150 so I'm a little disappointed waiting for the gold rush, so not too bad. It's.

C

Alright Heather.

A

For the first day had one over forty yesterday, her turnip prices, 19 terrible I, know it's bad, so bad. That's.

B

The stock market for you, man, it's.

A

True I'm, just waiting till time win till noon, wait until noon. That's the problems I got to get up early, but the nook and cranny doesn't open till 8 a.m. so I got to check it while I'm eating my breakfast drinking my coffee and then I got a check at noon again. So Kinsley says too many eggs. All the eggs I'm just collecting every single egg I, don't know what to do with them, but I am gonna, create a bunny bed.

A

Oh yeah! This is your first time on the stand up then welcome you're in for a joyous treat because animal crossing month over here notice. Getting we talk about all things in the world of xamarin, so we take a big focus on what's happening in the xamarin community. What you're talking about what you're blogging about and, of course, what we're doing in the open on github and what you're contributing and what we want your feedback on. Then we have some great demos as well.

A

Both Maddy and Pierce I sign them up somehow magically to give us a tooling update, even more tooling update from last week. I, don't know how that's can be possible, but there's that there's that so all right well Maddy do you just want to kick it off and go into it. I will.

B

Thank you. Yes, so will you drop those in the chat for me.

A

Live dotnet you can always go to live.com and the community links are right.

B

So I I'm in an internal preview of teams and it's really cool cuz I- could pop out my calls now, except I, can't find.

A

B

Of the buttons so I'm about I'm about half speed right now with sharing screen and muting and unmuting, but we'll get there. Here's your links who needs to capitalize month, not me March didn't happen. There's a bunch! There's a bunch I! Only at one I was going through the blogs past couple days. I was like oh there's like not as many blogs and then somehow they all just like unrolled onto my Twitter timeline. So there's still a lot, but I tried to cut them down to a reasonable amount.

B

First, though, before we get to the amazing community blogs, you all need to go check out. If you missed it, the dotnet can't focus on Sam rude event. It was last Monday to Mondays, not this past Monday, but the Monday before I passed, Monday March 23rd. It was fantastic.

B

There's 14, different things, starting with a nice keynote, Amanda silver came and joined me and Dave Dave's on staycation right now. Everybody is so feel free to tweet him all your problems. No don't do that. I do and a whole bunch of other sessions. Throughout the day, we had James and olya in channel 9 in on campus, like hosted remotely.

A

We were staying on separate sides of the studio and then we had mass.

B

A

Of hand sanitizer and then also wipes for every single time that we we stayed on the same side of the desk, every single time about 20 feet away from each other and then behind a glass wall from the producers. So we did a very good job of socially distancing and in the office where we could so yeah.

B

That ass profesh, there were some amazing sessions to lots of community members some familiar faces and we love C, so check it out, there's also the YouTube playlist. So if channel 9 isn't your jam, you want to just hit play and watch it all. There's a 14 videos. You can go through where's the time on this Missa I. Don't have the time. It's long, it's great like eight hours of content, just put it on open your animal crossing. Just do your! Do your animal crossing chores, open.

A

The gates, let your friends come in ravish, your town, you just binge there and that's what I do right.

B

Exactly yeah I have peaches if anyone needs them. Let me know, and then all the presentations from the day are also on github. So James did a great job compiling all of these amazing things, but they're all up here. You can go click like this. This person Maddy she did a talk. You can go click on it. She had a really informative, commit message. Download them take a look and kind of summaries of all the talks as well. So if you did miss it live, don't worry.

B

It's all still here it'll be here for eternity for perpetuity on the internet. For you to go, look at enjoy it and it was. It was a really awesome event. It was really fun and hopefully we get to do it again soon, of course, as always virtual xamarin, and.net events in April, so this month we're focusing on the virtual things, but there's still quite a bit going on.

B

You can see all over a whole bunch of user groups that are meeting up and trying to learn how to do like the virtual thing, as we all are, and there's also some information James put in this blog post about if you wanted to host a virtual meetup or convert your existing meetup to a virtual meetup, some advice and a tutorial with John Galloway who's, fantastic, so check all that out.

B

It's a really good resource and, of course, we have a kms Sam streamers, which is a list of our amazing people in our community who stream livestream when they're coding. If you are a streamer and you're not on this list, feel free to team teams, Twitter DM me or whatever I think David owns the list.

B

James might own the list, so it might take a minute for it to get updated, but we will get you on there all right, that's enough talking about us and how great we are, let's get into the community blogs, which are even better. First and foremost, um this is on the M factor blog. If you are unaware of M factor, it is a tool you can get for Mac in Windows.

B

Now, when does this new very exciting, but it kind of gives you these, like really beefed up sam'l and c-sharp intellisense and some cool at quick actions, image management, one of the things that I love about M factor and that I have been saying forever, like it's such a pain point when I'm using Visual Studio, it's just handling grids and so Matthew and wrote this blog post about how you can kind of easily create grids using M, fraktur and some of their shortcuts.

B

So in this one he says start with a stack layout and then they have a convert stack layout to grid refactoring, which is super. Nice there's also a whole bunch of stuff that, like it, helps you with the row and column stuff. So if you want to just really quickly I, don't know, add more rows and make sure that everything's in the right place, that's probably good example and frac. There will help you with that, so check it out. um Yeah.

B

The blog is great, there's whole bunch of stuff and, like I said it's on Windows, so on Charlotte's blog she has actually been working on UX when you're talking about runtime permissions, so things like in this one camera, Mike location, and so usually what you get is what you know the Android or iOS pop-up. That's enabled these, so the app can do its job, but Charlaine went and made sure that you know you can work around these things and give app permissions and a more intuitive way.

B

So that was really cool and she's got great gifts. Love me some gifts, so there's your allow, but it puts them on a button click. So, instead of when the app starts up, the thing says: hey accept all these things, it's just when I need. When you need the camera, you can click the button and then get access to it, and so, as always, there's code, multiple permissions, it's kind of a checklist using the beautiful xamarin forms check box might I add but yeah. So this is a really cool.

B

I, like this I love, all things user experience. So anything to make this easier is great all right. This is on medium by Boden and he actually reference back to one of Dylan's articles which I don't know. If we've covered on this particular article on community stand-up I know we've done some medellín's before because they're pretty great, but it's about confirming exit. So when the user will like lose their state if they leave your app or if they go back on a on a page and it's like you're gonna lose all this stuff.

B

If you hit back confirming that, so this is handling an actual back button on an android device. It's actually it's not a super long blog, but there's some good little code, tidbits in it and and there's a view model like actually making an interface or like handling the back button or exposing it making sure that works. Well, so cool and he's in the chat hi nice to see you very exciting, uh drop. What I guess your blog is medium, so I'll scroll back up, so everyone can take a look there. You go! That's I!

B

Guess by your name, sweet all right, Ahmed told us about I. Have read this like four times I'm? Still, not a thousand percent sure like what is going on I'm, not a link person, but it's basically creating a generator pattern. That's it it's an old functional programming thing, but using C, sharp and link and I just thought. This is a really cool, just like math e c-sharp blog and it popped up on planet.

B

Dameron and I was like what is this like have to do with xamarin and then I scroll down to the bottom, and he was like hey I built this I. You know the example was I wanted to build this app I want you to get it's like a math quiz score. So if you add the two numbers correctly, you get a point and not, and then you went when your score is 10 or not.

B

So that was cool and I like the bath stuff, because, like I said, I read it a few times and I didn't actually quite understand it, but it was cool to look at some, some good old c-sharp and what people are actually doing with xamarin apps in this. You know whole realm, so cool all right. Here's Gerald he's always on here. One month we will not have a jar. All the blogpost on this community stand up in the community part.

B

Eventually he will move all of these to the Microsoft dev blogs, because he does work for the team now, but I really liked this one. It was about databinding scope in xamarin forms, so making sure that you know when you have a ListView, that's gonna be scoped to a certain array of things, whatever it is and then it's gonna be date abound to all of the attributes of it.

B

So the example we always James and I use a lot is the monkeys and then all the monkey stuff, but what he did was he actually went published a sample about how he's handling this kind of problem and making sure that everything's handed and the write handled in the right direction and all that stuff. But it was a cool, quick thing if you are struggling with listviews collection views, carousel views, the BM that all the elements controls definitely check this out and and it can help you out with some of those concepts, all right.

B

A few more tiny SVG helper by daniel daniels great. He does a lot of cool packages and blogs. This one is pretty self-explanatory, tiny SVG helper. It is a very simple helper for using SVG's in your app. So I don't have Corona sorry, I have allergies, so I've been like sniffling, um but yeah, it's just literally like you can import the namespace use it in a markup extension boom. That's it love me.

B

We're gonna do it at 10 a.m. it's 117 yeah. They also did it at 9:40 a.m. apparently. That was a mistake.

A

We're live, did you did I make a good thing? I have the limiter on, did I mention we're live from our houses, yeah.

B

I seriously, I live in an apartment, building, everything's.

C

B

We're not even allowed to like go to our gym or anything. So it's been an interesting time. Okay, this one's a good old UI challenge. Dribble I like this one, because it was called exotic fruits and it reminded me of animal crossing, so I had to highlight it, but it was a really good. Nice I, really like this UI I, think it's got the nice mix of like cartoony and informative and and she does a really nice job, splitting it out and kind of analyzing the design into blocks, which I think is really cool.

B

Yes, so pretty I see from Pierce I completely agree, also just like a very aesthetically pleasing blog, so sync, fusion, amazing blog as always, but essential studio, 2020 ball, um-- one is out, so there are some new components and some some new features and all this great stuff, it's kind of like their their release, and so xamarin is the top of this, where they have new charts stuff. They have data grid, support for WPF and then also shimmer, which I think is great I want to see a shimmery control and some other stuff.

B

So sync fusion is great and, as we've said before, they have a community tool kit, but you know if you're looking for controls, this blog is really helpful and it's a good tool kit to check out, along with all of our other control vendors.

B

Finally, I saw this one right before the community stand up, so I am not gonna lie to you, I didn't give it the full eight minutes it deserves, but this by Chris and I wanted to call it up, because it's about mobile blazer bindings, which you might have heard of it's an experimental project, but it basically lets you use the blazer programming model to write mobile apps and that uses xamarin under the hood, which I think is really cool.

B

So this is a good example of how you could do that using the blazer syntax or the razor syntax I guess so. You know if you've never seen it before. It looks kind of like this I like to call it Franken zamel, but that's not what it is, but it tells all the things that it's supported. It links to Ellen's github repo, and it is very cool. So definitely check it out yes, and- and this this uh pending I wanted to also call out was, it does not replace, examine it.

B

Uses xamarin under the hood, which is very cool like the whole point of it is just letting you write a different syntax, but it still uses xamarin. So someone asked where the links to all these blogs I'll post it again. It's also on live dotnet right lots. They make that up. No.

A

That's correct, I, put I, put it right in there, so you're good to go. You're.

B

A

B

That is all the blog, so I'm gonna stop sharing benin.

A

And then to do incident then aren't I normally normally David is here to save us in the PRS. However, he's not so that means I have the honor of doing this. Let me hop over my desktop button and alright. So the first thing I want to point out. Let me zoom in over here dddddd zooming in zooming, in zooming in alright. So the first thing I want to point out is that by my own blog pull request, thingy, which is I recently aka yesterday decided to update my zamurai plugins github repo.

A

It used to be where I put all my plugins on my cross-platform api's, but a long time ago, I broke them all out into separate repos, and this thing was just sitting here and there's a thousand stars on it. A bunch of like people watching it and I was like you know.

A

What I really want is I want a definitive list of all the things that people should use in their app so for dotnet, xamarin Windows, whatever you're doing here, are things that you need so I point out, xamarin essentials, shiny, so kind of like this is the stuff your app needs. This is stuff, that's complex, that's made easy and then open-source plugins- and we have this in a few different places, but I wanted to make it easy to update where it's not like. You know complicated and different repos kind of very community feel.

A

So you can go and add yours in here, so you can go and find all the different community plugins. So things that aren't available and essentials are shiny are all here so media meteor manager, screenshots people have already put pull requests and added theirs in here data. Caching, databases are in here some awesome, dotnet libraries. So if you're making like those tiny things or sockets or eeehm helpers I put in here, if you have great helper libraries, you can do a pull request.

A

All the great mvvm frameworks out there, whether it be big or small, put them inside of here just kind of give them a nice little breath here and then also UI control vendors. So here's a bunch of stuff, including that awesome video that we made, which I think is really cool and then also UI, controls from the community, so I always find have a fart hard time. Remembering where is that control like? Where is that thing at so like the bottom sheet?

A

Breadcrumb I thought this one was so cool I got a pull request in on the breadcrumb and my computer's on fire, so we'll see if it loads up over here. Oh here we go and this one's cool because, like if you're creating like a website or need like a navigation stack, this will add like breadcrumbs like used to on the web, and it just adds them automatically into your navigation sack, which I thought was so cool. So you can just make a pull request.

A

Anything you want there's utilities so things in here for like as your dev ops or just your resizing images. Things like that, send a pull request down, accept them, I review them just put them in alphabetical order, there's no a no bias. It's just alphabetical anything like that, which is cool. Now, some few PRS we'll start with xamarin forms.

A

The first one is touch gesture recognizers, so there's a few different implementations, this by KSM I, think go, and this is really cool because he introduces like generic gesture recognizer similar like iOS, but there's like touch points and touch events and all sorts of different like enter, failed, cancel, move. All sorts of things works on every platform.

A

He kind of shows like what it would look like like when things are touching moving things like that, and you can even put it into the visual state manager, which is cool now that one still open so it still pending on there and a four six o type of PR other one here is from rui so from the team, this one's very simple carousel view loop, and that's that just one boolean, if you want to loop it, which is really really cool, which is nice I'm.

A

Looking at my drop frames, I don't have any drop frames over here, so let me know if I could just be YouTube and then cross-platform stuff also OS themes which are really really important, which I think are nice. So if you're looking for some OS theme support, this is in for six. Oh, so specifically, this is Gerald over there talking about OS theming things like that that are going on. So he has all the different app colors themes. Things like that going on looks like YouTube might be helping some issues.

A

Anyone want to check the youtubes out I'm, showing very much.

B

Which is having an issue hmm I'm.

A

Showing a lot of green on my end, no drop frames, which is very strange so.

B

Youtube looks good, but my twitch is not oh no, but everyone on YouTube is limp. The comments alone, I hear no.

A

No, no I'll push on I guess the.

B

Team's call is fine, James, do you if you turn off incoming video on team, so let's grew up. Let.

A

Me see you really quickly. Yes,.

B

A

Yeah I could probably do that. Let me try that I. Don't do you do all right? Let me see here.

A

Let me go back over to the desktop. Well there's that off, hopefully that is a little bit better, we'll see: yeah, I literacy, zero drop frames, so I'm not sure.

B

Yeah now we're getting comments on from twitch.

A

Do-Do-Do-Do-Do-Do yeah I live and see zero drop frames, CPU usage minimal. Oh my.

B

God, oh the video is frozen, but they can hear us. Okay, oh really,.

A

B

A

That's interesting: um hmm can they see it, let's see if they can see him, yeah I can definitely.

A

Oh interesting tabs take a lot of memory. It's not working on YouTube Maddy. Do you want to pull up your else? Yep.

B

Let me do it all.

A

B

Try to go all for you, let me get the legs to.

A

Show you right on the thing which is cool dot.

B

Dot Det pause where, oh, where are the leaves their.

A

B

A

Be on community: let's see if I don't share my screen. If this works or not.

A

Question mark question mark Oh.

B

God Pierce.

A

Is back, let's see me not sharing my screen works or not yeah.

B

A

To find it did you do.

B

B

Copy link well.

A

That sound is great, though that's always important. Yeah.

B

If I guess, we don't sound bad, although if the fire alarm goes off again, no promises. Alright I'll show my screen. Alright,.

A

See if that works see, if that's.

B

Better share what caris love you? Yes, Ross platform.

A

Os themes, alright.

B

Open all these for ya, okay,.

A

B

Ready to save my plugins great, alright check it in with the crowd. How are we looking any better? Hopefully,.

A

Question mark question: mark the.

B

Video is still lagging community podcast. That's great Lewis I, like that. That's.

A

True, that should be basically back to where we were so.

A

B

The twitch link is it's twitch.tv, slash, Visual Studio, it's the same run developers YouTube and then you can also watch it on my net and mixer right. Yeah.

A

I'm gonna check it out really quick here: I'll chickity-check it it's kind of working, but not as smooth as I want. hmm There's a dog.

B

My dogs, under there it's.

A

Definitely laggy I can see from this.

B

Where you start your PC Oh, No, Oh, Dan just refreshed and said we're much better thanks, Dan, nothing like a good old refresh.

A

Okay, now it's all good all right, so yeah.

B

A

My surface book doesn't like to do that all right. Now we're good we're back to where we were we're totally good, we'll clip it all out. No big deal. It's all working, everything's, better I closed edge, close all the tabs. hmm All right thanks everyone! Thank you. So much for hanging out. You know this is the first time from this PC I'm, usually on a different PC. So now everything is good butter smooth! You know what I'll do next time is: I will do a capture card so that way, I'm just.

C

A

A different PC thanks everyone for hanging out, it's all good butter, smooth, lovely, lovely, lovely whoo. We made it all right, all right, let's go through these, and now we just no I can't do it. I can't do multiple things on this computer and that is good to know how the power of a surface book from a few years ago doing a lot of things and also you know, I think the thing is I bet it's, because I'm I have an HDMI out, which means it's like powering two screens right now.

A

I bet, that's that, oh.

C

A

All right cool chat rooms, happy everybody's, happy, everything's, better now, OS theme support so actually we're implementing this. What we're implementing this over in I don't know what happened there. That's weird boom the Refresh step-up we're implementing this over in xamarin essentials. There's already theme support, so you can detect it, which is nice, but they're. Adding this into xamarin essentials as well. Our examine forms I mean as well, so there's some feedback here. The idea is to swap it out, use amber and essentials under the hood, but still have a public API.

A

So they're just have this in here from Gerald, it's going in at some point, hopefully for 600, which should be good next all right. We got another one from Gerald, so this one's actually merged. So this is a very small one, but what this does is its optimizing xamarin forms to work with the android date night mode, so this is very nice. So that way, your application automatically updates based on the theme. So this is there's really nothing in here, but you can just see from the pull request. It's one file.

A

They pull in the theme for you automatically if you go to files changed instead of having like a base theme, this uses the day and night theme and you're good to go so that way things are BETT tire. Next, one small update here is for: u WP shell, which is still under feature flag, but this one adds a background color.

A

So if you scroll down there's a screenshot of it and it's green, so you can change it so they're flushing that out making it updating it as it goes, and you can kind of see all the things happening there, which is looking really really good, so Xavier put that in there. Next one is from the the the Tizen team. Actually, the editor PR for HSV support, which is hue/saturation color, which is super duper cool, and where are you gonna?

A

Add this to xamarin essentials we like to keep the color API in check, so you'll see those back and forth so if you're, using HSV you'll be able to get that cool all right now over to xamarin essentials over here is a really cool pull request from the community. We've been working with Janus for a while he's been working on the geolocation functionality and specific altitude, so the problem that he found is that between iOS Android and Windows, they all use a different altitude system.

A

So what he's doing is is he's pulling in the altitude reference system, so you know if it's like a geode or if it's like different different ways of doing it, and this one will be pulled into one six-oh, which will be our next release. So that's a really cool one, so there's no really way to xamarin essentials, won't like mesh them together and standardize it for you, because it's like crazy dependencies, but at least it will be there for you, this one's cool I know nothing about geocaching, except for I kind of do.

A

The idea here is is a great pool request. Can you hover over his name again on there? So I can see his name pop up litter didn't ya shovin draw. He did this pool request, which is cool, which is geo, hashing and geo.

A

Hashing is that you give the latitude and longitude, and then it gives you a unique code back and then you can always get a unique like adjacent square of north east, south west and a block basically say how many blocks away do I want to be or how big is my block ratio, and then it enables you to sort of have this unique code for where you are in the world instead of having to memorize latitude longitude, it's completely cross-platform and it's based on this Gustavo's geocoding system, I.

A

Think it's really cool, so I think we're just gonna pull it in so I know all right next one over here um this is similar. There was from HSV. This is a to HSV. This was actually asked from our seeing AI team who asked for this and Pedro said I'll. Do it? Why not so he's gonna put in?

A

He did the two HSV and he's also gonna put in the from HSV and then we're gonna get that into one six Oh, which is cool, two little color helpers and then the last one from Eadie Snyder, which is super cool. This is a draft that we're looking up four one, six zero, which is actions. So this is when you like long press, your app on iOS or Android that action sort of come up. So here he's looking at you know how do I you get and set these values correctly.

A

How can I see if they're supported or not? How does it negate into my application all cross-platform, which is cool because these can be set at runtime? So that's really really cool. So love that and those are our community pull request. Then Anna did it to give the commander.

B

A

Computers on fire, but we did it so it's okay.

B

A

B

All right, well, I'm, not even gonna, start on sharing Andrea sharing my screen, we're just gonna hop right into it.

B

Alright, uh-oh so I'm going to show us some short, some quick things in vs, Windows I know you all have heard me talk enough today, so I'll turn it over to Pierce, but he's set up to show on Mac, so I want to do the windows stuff, real, quick- and this is a preview build so keep your eye out for when this is gonna, come to all of you folks, but right now in all Visual Studio, previews and I believe in GA as a preview feature and I'm, unlocking my iPhone while I do.

B

This is hot restart. One is hot, restart great question. Well, it is a way that we are. We call it like a diff and deploy, so it builds like a subset of your app just what's changed whether it's c-sharp everything project changes, adding images and it just spits those changes over to your device, and you can turn it on in environment preview features, because it's a preview feature. Yes, it will eventually go to the xamarin features, but while it's preview it lives with all the other amazing preview features we have across Visual Studio.

B

It's right here enable xamarin, hot restart, and so what it does is it really speeds up your build and deploy for iOS projects. Now iOS projects will does that mean I have to be paired to a Mac, well, not for debugging, because what you can do with how it restart is actually plug, just your device into your PC and get started. So this is my iPhone. It's a physical iPhone in my hand and I have screen mirrored it and I want to build it to play this BAM.

B

It's gonna, take a second my.

A

Phone plugged into your Windows machine there I did.

B

My Windows machine this thing popped up, but well we'll talk about this in a second but I'll just go and I'll change this to just forums, hit, save and just like that and updates is.

A

That what did they would have.

B

So I am now hot reloading with hot research whoa. How hot is that I need a Paris, Hilton gif every time, I say that's hot, about our hot tools, so high reload is when you make changes to your zamel, you can hit save or you know we'll talk about what else you might be able to do and see those changes immediately reflected on the running app, so I can just type some stuff and it updates right away, which is beautiful. But what is what is this? My file isn't saved. Also.

B

What is this thing over here? I, don't know! Well, if you have ever done windows developments. Let me stop this before I break everything. Do you have it on windows development? You might be familiar with the windows, how it reloads so I'm gonna drag over Visual Studio number two gosh, it's a good thing! Monson trying to do this demo I think the stream would be at like half a frame per second right now. That's.

A

My cell, to up for it so yeah.

B

Exactly all right apt to going to place my local machine BAM, give it a sec. So.

A

This is just like a WPA UWP yeah.

B

A

Xamarin forms application is normal right. This.

B

Is yep: this is a plain old, ewp application. It's very intricate I wrote the word high and it's in dark theme. Cuz, everyone loves dark theme and I can go in here and start typing and it updates without me. Saving. Oh, look, no save ant I can click in here and see all the things in my sample page and then, if I, like click around I, go to my apt on, say I'm on I'm, like oh wait: I need to go edit. This text block right-click.

B

On that little thing it takes me to it in those amel. I know. This is all cramped. Trust me this. This is like not the resolution. I would normally code. Add I hope. But oh that's amazing! Oh no! This is a uwp project, but wait.

B

It's gonna come to xamarin forms like I, showed you with this app, so I'll redeploy it I might take a second, but we are working on and have been working on for quite some time now, combining the way that we did sam'l hot reload, which was just kind of the way we could get it out the door and the way that we wanted it to work as quickly as possible, right which we just refreshed the entire page.

B

We are working to integrate the way that we do it with the way that Windows does it, which is instead of refreshing, the entire page. They just refresh, what's changed in its children and also you don't have to require save. If you like to save, you can keep it on save but, like you can tie it, and it's just going to continue to update as I'm changing things and with we're able to light up.

B

Some of these amazing features, they've built for the window side of things like the live visual tree, so I have this this um label and then, if I click, my little thing it takes me to my label. In my example, so these pictures will start rolling out. They're gonna be preview because this method, since we've kind of taken it over from Windows and we're working really closely with them. Obviously, windows and xamarin have different api's and we have to handle that. So there are still some limitations.

B

Eventually, we want this to be your default, but for now, as of the next review, that's gonna come out for a visual studio you'll be able to actually turn it on as like a preview idea. So if you're on the newer xamarin forms which are required for it, you can switch from entire page, which is what it is now, which is the flash changes only and try that out. So it's gonna be very exciting.

B

Like I said it is gonna, be pretty limited off the bat right, because it's just kind of this whole new way were doing it. So we are excited for when 16.6 preview 3 comes out for as many people to try it and and break it and tell us how to break it and how to fix it. So we.

A

B

Get it out to people as soon as possible, so.

A

Feel free to ask questions in the chat. A lot of people are going nuts right now, I'm glad that we got the stream working again and that you're demoing this so I want to make sure that there's a few things that I'm recognizing here so hot restart, which is rapidly iterating on your iOS application from Windows well starting with iOS. That is a preview feature, so environment under all preview features that are like.

C

A

Thing isn't in the product, yet you turn that on now you have to like have an Apple account sign in and then.

C

You can deploy.

A

To it right, that's available and stable today, under this feature, flag, correct. Is that correct statement correct.

B

A

Okay and then 16.

B

A

V, it's there now hop zamel ha reload, which works with any xamarin forms application iOS Android, whatever that's already been available for like ever right. Yes,.

B

A

Year, eternity.

B

A

Today, yeah and that's a new feature that you're having there right so there's two things: this changes only and then also the on save or not on save right right.

B

A

Do you turn on and off so.

B

Right now, if your on changes, only it's just gonna, do it automatically? It's not gonna, do it on save and what what we've done is because this has been such a cool collaboration between the windows team and us, the windows tooling team, so they the people who built their hot, real it and there's amel tools.

B

They have actually gotten a lot of requests that people want it to work on, save so we're working on sharing that functionality so that you can set it to be on save or not on same across all your different hot reloads, whether it's its windows or Sanford, forms, and eventually that will you know, will combine the experience even further if they have something really cool like a live property inspector, so we want to make sure we get that going all those things. So there are a bunch of questions.

B

Is this a preview we can play with or internal? Only this will be a preview shortly. I do believe this button. You might see this if you go into the preview right now, but it doesn't actually do anything. It might do a few things, but I would recommend keeping it on this until 16, 6 preview 3 will blog about it.

B

Well, we'll keep you posted. We just wanted to get you guys going with the latest stuff as soon as possible. Will this work for c-sharp created you I know this is sam'l only but c-sharp hot reload, all up UI or not, is definitely something we're looking at. Hopefully, we'll have some updates for you on that. You know at some point: 2020s felt like two decades so far, so I have no gauge of time, but you know eventually and and I posted the code updates question as well gesture recognizers. Yes, we have heard about that.

B

We're getting. There appears, got it sweet so.

C

Just to be clear, what we're doing here is before was a maja reload, the one that's in stable today when I hit, save we're reliving that whole page right, yep, and so with this change. All that's being reloaded is what I've actually changed, which is pretty neat so that, obviously you saw the same effect here where you can kind of do the continuous editing style thing, but that's going to give you faster reload, that's going to give you a more reliable reload.

C

We have a pretty cool video of an app where there's an actual video player in the application, and you hit babe and the video keeps playing because we're not updating that video element. If you don't update it, we're updating everything else, and so you're gonna get way faster, heart, reload and more reliable, hot reload. So.

A

Like if you are a Madi at a let's say, an entry on the bottom or in the top of it.

B

A

Gonna see if this works and then said that don't set the text to anything right right.

B

A

B

This is I might just switched back to the old reload style to show you that when I hit save here, it's.

A

B

The whole screen yeah.

A

B

And then the entries I don't miss a hurry is on.

A

That you put some put some Pat margin in there. Really quick I want to test something out. I want to show off why this is cool, if it's I guess margin, actually sorry 100, padding, 100 padding, so maybe maybe a hundred and fifty there you go so.

C

A

You type into that right, yeah.

B

A

You type into there and you say not.

B

An emulator there's.

A

Not an emulator, so then let's say you change! Welcome to xamarin forms right.

C

A

Should go away right.

C

A

See how it went away at the type so now, if you were to do the new one I'm, just testing I have no idea. That's worse! I've, never seen it.

B

I have no idea that this works either like I said, this is a. This is a fresh off the build, builds so we'll say.

A

Let's see now where, as asking, how do you mirror that you're using an app called reflector, correct, I am.

B

Yes, reflector is fantastic, I'll type, some stuff in here.

A

We'll see I'm putting.

B

It to the test.

C

A

Though I have never seen it so um fingers crossed.

B

No, no uh-oh I think we upset it James. Okay,.

A

I upset it so there you go. That's.

B

Okay, like I, said this is this is pretty pressure, although I know looks like a live visual tree to me. Whatever. Oh no big deal wants true, we'll get there but yeah. This is super exciting. Where is it so capable of dealing with zem ours?

B

Yes, yes, the way we handled the saml errors we actually copied from the windows team in the first place, what we call route edits, which is when it gives you the squigglies, so it says like okay, your color is thought wrong, so that will still always be there, which is fantastic, but I'm. Gonna. Stop sharing my screen now and stop talking and.

A

C

B

It over to peers.

C

I'm feeling good feeling good what day is it I'm a blues and track I believe.

A

B

C

Cool yeah I mean one more thing on that I really like it shows how much like xamarin being a part of Microsoft like is really kind of paying dividends. Like last year, we spent a lot of time working with a team to deliver the sam'l editor and visual studio format, and that was bringing over code that was already read and making it work with xamarin forms and then porting it to Visual Studio for Mac, and this is a continuation of that right, like we are taking advantage of the same pipeline.

C

That's powering what used to be called sam'l edit and continue. What's now called sam'l ha reload for Dada desktop platforms and what I love about that is like I, get a consistent experience across these network loads and that's something we're really trying kind of more stylistically to drive like if you're a.net, developer, using xamarin should feel comfortable to you. Let me know when you can see my screen, so I'm gonna briefly run through. Can you see my screen.

A

C

Good to go maybe.

A

C

A

Down the little video there see that little yeah.

C

Sounds good, okay, so yeah just quickly Maddy mentioned 16-5 release I just wanted to quickly run through this. This is now stable. So this is what you can get today in Visual, Studio, stable, I'll also run through vias for Mac and what's new, there Maddi already showed off hot restart, which is awesome. We kind of are envisioning this progression right, where, like you, have hot reload, where I can hit save my changes are applied, I don't have to rebuild them redeploy and my state's maintained, and that should work for the majority of our changes.

C

But there's always gonna be changes that don't fall into that, like maybe I'm hitting multiple files. There's rude edits like Maddie was saying: hot restart is supposed to be the fallback for that, like you can always do a hot restart and we want to roll this out to iOS and Android on Mac and Windows, and the cool thing about how restart is you're getting because Madison, it's a different deploy, we're only actually recompiling the assemblies that have changed, and rather than recompiling and redeploying your entire application, we're only deploying a dip.

C

So the effect there is that you're gonna see much faster building the POI times we're seeing some customers report up to like 2x faster with hot restart. So that's pretty freakin amazing. As far as other runtime iteration things we've been working on and when I say runtime, iteration I'm talking about this group of features and enables me once I have an application running on my device and I'm debugging to make changes without having to build on the poi again so apply changes. People been asking about Android hot reload, it's kind of like that.

C

So if I'm tinkering with things like my Android layouts my streams, my colors, whatever it may be in my android resource directory I can use something called Android apply. Changes I can hit apply changes. It will basically do the same concept as hot restart. It'll do a diff and deploy and the cool thing with apply changes actually.

C

Is it uses the the native Android State mechanisms, so you have existing State in your application and you do an apply change and you've wired up all your State through the native Android stuff, the way you're supposed to then that state will actually still be there after you after you do an apply change. So that's really really neat multi-target reload. This was a big change that came in 65 as well.

C

Basically, the ability to reload changes, majors amyl across multiple targets, so you debug to ios and android at the same time, hit save and you can see it reflected up both. We did this feature because we heard a lot of feedback from the community that you like to iterate on both at the same time, but right now that's kind of difficult. You kind of most most customers we're working on one and then would come back around later and actually edit the other UI.

C

We wanted to make you more productive and be able to do both at the same time. Of course, there's always a performance, app size, startup stuff and every release. That's a major theme for us. Sam'l document outline is also new, so you saw the live visual tree. This is kind of a similar concept except you don't have to be running. It's not live, obviously, but it shows a hierarchy of your zamel, which is pretty neat and you can actually opt out of using the sam'l previewer so at xamarin and when we're building these tools.

C

Obviously we'd love for you to use the tools, but we want you to use what makes you most productive and if using the sam'l preview, isn't a productive experience for you and your team sure you can go turn it off. That's totally cool with us, so that's also new in 65.

C

So that's all stable, I'm, also gonna run through ps4 Mac, a lot of the same things as we try to deliver all the features on both visual studio and visual studio for Mac. At the same time, so same things here with sam'l ha reload, apply changes. Android startup in the dock outline another cool feature, I'm excited about which we heard from a lot of people is they're like I'm, more way more comfortable using Xcode to build my native iOS, storyboard, UI's, and so before.

C

You kind have to do the right-click open, an Xcode thing which was kind of clunky and so for those people who prefer to use Xcode to build their storyboards. We've actually made that a lot easier in 8.5 release, so you can go get both of those in the stable channel I'm gonna shop staring my screen and I'm gonna bump back over to my Mac, we'll see how this works. The old multi teams joined from multiple machines. At the same time, experience very scary. Let's see here, share screen 1.

C

So let me know when you can see this all.

A

Right, you are good Wow magic. That's amazing, magic.

C

Amazing same person joining teams from multiple locations; ok, so we've been covering some of the runtime iteration stuff, but a big part of that. You know if you're gonna be iterating at runtime and you aren't using a visual designer or a design surface of some kind to actually check your changes that you're typing a big thing that will make you more productive, is editor improvements and so on. Zamel we've already done a whole bunch of stuff work with our sample editor team to deliver some awesome stuff. Obviously, outside of intellisense, you get Intelli code.

C

You get all these completions, you get some basic analyzers and things like that, and so we've heard a lot of good feedback about the zamel, editing, experience and visual CD and visual studio for mac. But we also wanted to bring a lot of those improvements to indra native as well, and so I'm going to show off some of the editor improvements that we made to our Android XML editing experience. So first off I just wanted to say a change we made recently, which a lot of people had been asking for.

C

Is you can actually name your layouts dot XML? They don't have to be a XML anymore and so for people who do like using Android studio to actually design their you eyes great, it's the same concept as Xcode and the preview before we want to be used, the tools that make you most productive and so we're trying to make it easier to enable those scenarios. So here you can see this is already actually in a visual studio formats table, but I wanted to kind of recap some of the stuff that's available here.

C

We have a dot XML file, it's my colors dot XML file. So this is my resource directory for my Android app.

C

This is where I'm defining basically the sam'l equipment of my resource dictionary for all my things that I'm using my application- and you can see we kind of get some cool in line editor stuff like I, get hey what color it is I'm Mecca night I can come in here, I'm, not very good with things I, don't even know what will happen if I change some of these things, because I'm terrible attacks but yeah you can see like if I was to just change these to all s.

C

That's too many else, all right! You can see it updates in real time, and so that's pretty neat. If you're anything like me, you have like a separate browser window. I've been trying to play with these color palettes and it's always a pain. So that's pretty neat. We have this already available in Windows and Mac.

C

So everything on the show here with Android XML editing is also available on Windows as well, so something that is new coming in this current 8.6 release in Visual Studio 2019 version 66, which is currently in preview, is we've really expanded our Diagnostics engine, and so this kind of comes as a consequence again of the runtime iteration stuff.

C

If a designer is not going to be telling me exactly what is wrong and right with my code that I've added, maybe my layouts, not quite right or I've forgotten an attribute I need to know about that, and so we really invested a lot and actually adding kind of some tooltips, some Diagnostics to the Android XML, editor and you'll get a lot of this for free by default. You don't have to do anything special so like, for instance, you can see here I'm not explicitly stating my orientation for this layout.

C

So it's gonna give me a warning on that down here. It's gonna say: hey I, can't this this resource URL. So if you have a resource URL that you actually think you have created but not actually have created before you would run your app and you'd, be super good because you'd be like why what's happening with my color, what's happening with my string resource and you never knew what was happening now, we're providing all these tips in line and even like some general, like hygiene stuff.

C

So like right here, we're like you probably shouldn't do this. You should use a string resource and so we're trying to help you build better applications with what we put into the Diagnostics engine for the editor, a really cool thing that we're doing obviously with Visual Studio Visual Studio for Mac. You have this thing called editor config and you can say: hey, like my team likes the right source in this particular way, and you can kind of define some stylistic attributes of that code for bringing that same concept to Android XML editing.

C

So, essentially, what I'll be able to do is I'll, be able to say, hey, like we're, gonna enforce a rule that all of our strings have to be defined as a string resource and can't be hard-coded, and so you can set all these attributes and actually say for my application. These are the rules that we're gonna have. So that's pretty neat in addition to the obviously the default rules. You're getting I already mentioned this earlier, but another cool feature that we've lit up in 86, which is brand new for Android XML editing.

C

Is we brought in Teleco to Android XML? So this is awesome, especially for people who are maybe a little spoiler bomber in Forbes, so like I can come in and the cool thing that I like here is I'm. Actually it's telling me okay, these are the attributes that I need to set. These are the most popular and I always joke, because it's kind of like all you do have to do is hit enter, and it's kind of true you just keep hitting Enter for these things and it'll keep suggesting things. So you can see.

C

My suggestions have changed now that I've actually added my layout height and I get some new ones here, and so that's a pretty neat feature. That's coming in 86 that'll be available in Visual, Studio and Visual Studio for Mac. These are a I powered, intellisense suggestions based on open source repositories.

C

So we think this combined with the improvements we've made to the Diagnostics engine combined with some of the neat little editor tricks like showing the colors in line are going to help you to build better Android native applications, so that is all I have the show on that I'll see my screen.

C

So yeah, that's what's new in tooling, lots of things are happening. These are. This is obviously just a small look. We'll have a blog coming up on the Samara blog, so deaf blogs at Microsoft, calm for Dameron and and we'll be covering all of these kind of as an overview, probably with preview 3, which is coming in a few weeks as well as kind of like Maddy, said deep dives on some of this. So you can really understand ok for incremental zamel reloading.

C

What does that mean for me and my team will have a dedicated blog post kind of describing some of that as well? So.

A

Stay tuned cuz he Maddie's got her serious face on responding to people, confident cool, so a bunch of good and race I mean in fact I did I.

A

Did an episode of the xamarin Chevy go to xamarin, show calm with Jeremy love all who works on our Android, tooling team, because he's do the the engineering lead of that team and I was looking for feedback there and they've done tons of stuff over the last year or two that we've talked about at dawn net comp at you know the summit like a whole bunch of things to definitely be on the lookout. There I entered a bunch of good questions about like SDK projects coming like done at 5:00 timeframe.

A

You know one thing where people like what, if I run into this issue, or this thing doesn't work things like that, you can always hit that report, a problem button in Visual, Studio and Visual Studio for Mac. That SuperDuper helps out the team in general. So definitely be aware of that. If you've never done that before so there's that anything else I don't know. If there's any other good question of most people ever I, think I was on the asp.net one I think they have like nearly four hundred people.

A

We looking like three hundred people on the stream right now, which is pretty awesome.

C

It's also thanks.

A

To everyone, that's doing it yeah and I put in a cool strobe light there you go everyone's.

C

I wanted that mister I wanted to shout out the community actually, because all these features are driven by your feedback. If you ever get a email or there's a notification and visual Studios saying, please leave your feedback. Please take the time to do that. I. We literally get thousands of responses on those surveys and we read every single reply. Often if you leave your contact info, we'll either email you or or schedule a call to follow up on some of the feedback you left and all of those feedback.

C

You leave in those surveys, whether that's in a survey interview other forum on Twitter on a developer community suggestion to get all of those help shape this roadmap, and so these changes that you're seeing here are the cumulative result of the feedback you've given us in this survey. So please keep doing that. Please keep trying the previews and, like James said you can always report problems via help, send feedback report a problem, and you can even report suggestions there too.

C

So if you're, like you know, I like this but I wish I had that you can also do that from within Visual Studio. So thanks to the community for helping to drive a road map, yeah.

A

And also a lot of people are always asking we're thinking it started with stuff. You can always go to dotnet. There's a lot of learn articles there for xamarin I'll put these in the in the chat too. You can always go to aka.ms/offweb.

A

Unch of great tutorials on learning anything really a Microsoft channel 9 has great c-sharp tutorials, there's in-browser tutorials a whole bunch of good stuff. There curious Drive was asking about any updates on the mobile blazer bindings. um You should we talked about the blog post that Maddy put out I would definitely you can just go to the github page. It's an experimental project. Elon is working on it. He did um some cool updates recently for it, adding more controls and whatnot, but check out the asp.net blog.

A

That's where that will live, because blazer mobile bindings are really for web developers to build native mobile apps right. So when you have a building with xamarin, your client developer building desktop mobile applications, but when your web developer you're used to web developer things, so that's where the mobile blazer bindings come in. So that's always how I explain the world is, like you know, there's different types of developers that are used to certain you know. Architecture patterns like different syntax, like Maddy, was talking about with razor syntax.

A

So, if you're coming from a web scenario, we're like I'm an asp.net core developer or I'm, creating a blazer app I want to reuse a lot of that stuff over in the you know, mobile scenario: well, that's where mobile blazer bindings come in, whereas, like hey, I'm, a UPF developer, I want to go build mobile, apps like well, that's where xamarin xamarin forms come in. You know what I mean so, which is great. Oh yeah arsalan asks about pragmatic, UI, so coded UI.

A

In fact, there is a great we talked about in the last community, stand up, but there's a great pull request. That's in the current preview or in the current release. I think it's under feature flag, but it adds all these extensions to coated UI. That makes it really really easy in general.

A

That's really great so definitely check out that it's called like c-sharp markup extensions, which is really cool, gives you that type of experimentation there, a lot of good info for iOS and Android anything for Mac, OS updates, well, Visual Studio for Mac I, don't know on the Mac OS side of things. There have been more pull requests into xamarin forms and more work done on the bindings, but Nathan you definitely hit us up on twitter.

A

If you have specific questions and point you over to chris Hammond's he's the go-to on the iOS android side, Jerald asks any new books, including shell and collection view, I'm, not sure ad Snyder just came out with a book which I've linked in here before you could write a book not-not-not us. You could write a book community, there's 300 people I could write a book. So there you go, mm-hmm that'd, be cool, I, think! That's it anything from you. Maddie no where's.

B

My unmute button I found it no, but thank you I mean I, just hacker. What Pierre said. We love our feedback. We love all of you. I know cliff said he hasn't seen a survey from a Wyatt for a while from David. Well, that's because we do them inside a visual studio as well, so a lot of the ones recently. If you see that little gold bar pop up and vs it's like take a survey, that's actually us.

B

We, we program those to show up to be random yeah as it's fun as always, and send me your links for next time, because I always forget them like I, missed Dan, Siegel's, amazing, new project mobile, build tools which I dropped. The link for in the chat definitely check that out Dan. If you write a blog about it, I'll put it in the blog post for sure so yeah yeah.

A

Man Dan I was asking about oh yeah, Mac OS you're right, we did announce at Donette, calm, focus on xamarin event. We were working on mac, OS support for xamarin essentials. The pull request is basically done. So definitely check that out. That should be hopefully going in 1.6, which we're very excited about and you'd be good to go. Yeah.

A

um That's basically a Raul, yeah I. Don't think. There's any updates on the xamarin test recorder at all that different team owns that product, the the App Center team, so they they do all that stiff I. Don't think there are any updates, I, don't I think they have deprecated it at this point. So I don't think. There's any updates on that at all. Everyone loves my strobe lights. Thank you very much, they're very cheap on Amazon I was buying expensive lights.

A

Cuz I was like oh, this will be great, like you know the hues and this and that and then they just weren't bright enough, so I just bought this one I saw an alfa gamer that he had recommended this. This light and it's just a 50 watt, powerful light and has this cool controller no, and no one Madi and Pierce can't see me cuz I turn off my webcam, so I don't think that that was the problem by the way. So now Maddie can see this cool. It's like you know: generic, oh I,.

B

A

Asks any plan for material design and we have material design and zammurd forms for both iOS and Android with visual. So you just turn that on flip it on right, there Dennis as well as amber and be available in da at 5, I'm, doing lightning questions yes boom.

A

um What about constraint, layout, I'm, not sure about constraint layout, but yeah material design is already there image. Picker pull request is in our oh look at that and of course you can go to live dotnet, we'll post it one more time in here. You can always find a link to all the blog posts and all the videos that'll be good. I.

B

Just tried to set my lifes to purple, but they're, not strong enough, so I guess I have to get the James one yeah.

A

Right, that's the problem that I had Bart I had purchased like these Phillip Hughes ones that were nice, there's more brighter yeah.

B

A

The light effects right, yeah I'll, send you this video from alpha gamer and um so I ended up by selling all of them on on eBay, so at least broke even and then I bought this one. It was like I'll. Send you an affiliate link, so I make two dollars off of you. So that'd be good good questions. Robert was asking geo hash, hopefully 1.6. The nice thing is people can always go into any pull requests and it has a green checkbox. You can grab the new get today.

You can just grab it and try it out, at least which is cool, a constraint layout system. You can use absolute layout that can train sir will the worst but I don't know it's a good question, maybe put in a spec for that Nathan for what you're looking for specifically, there might be one already I'm always looking down here, because the questions are down here, but then the cameras up here and that's when I'm in the studio, everything's so much nicer in general. So there you go alright, that's it thanks! Maddie thanks, Pierce bye, I.
