 Hello everybody, my name is Martin Siegmund. I would like to tell you something about Uno platform in this short talk. If you built some cross-platform applications before, you might know that building them is very hard, because you have to target multiple different platforms, each having different native language and different UI framework. Uno platform is an open source solution that lets you simplify this by building your application as a single code-based application and then deploying it on Windows, Android, iOS, macOS, Linux and even WebAssembly and the web. So this is a free and open source solution so you can find it on GitHub and contribute and send any feedback and I will now show you how it looks in action. Here is a very simple Uno platform application which is written using XAML and C-sharp, so both languages which are very commonly used by .NET developers. And this application includes a very simple UI and very simple code-based in C-sharp. Now the application can be run on all the platforms including the Windows platform. So this is a Windows application. Here is the same application running on Android with the same behavior, same application running on Linux. This is running in the Windows subsystem for Linux. And finally the same application running in the browser. And as you can see, this is running using WebAssembly. So if I do any changes, there are no server requests, this is all running on the client. It's basically C-sharp and .NET running in the browser. The very cool thing about Uno platform is that it gives you a lot of UI controls that you can use out of the box. So there are things like buttons, checkboxes, combo boxes and so on. And all these controls are available in multiple different themes. So you can pick the Windows theming, you can pick material design which looks more like Android application and you can also pick Cupertino design which makes your application look like iOS application. And if you don't like any of these, you can also style and theme your application exactly as you need because you have control of every pixel of your application. In addition, all Uno platform applications respond to theming of DOS and you can even switch the theme of your application manually so you can see how the same application looks in dark theme without writing any specific code. But Uno platform does not offer only these APIs for UI, you can also build your application using non-UI APIs which are fully closed platform as well. So you can check for connectivity, for example here is a network information API. So if I check for connectivity, I can see I'm connected. And if I switch and the browser to offline, you can see it switched automatically to offline indication so I now know that I'm not connected anymore. And this is a fully closed platform API so you don't have to learn how each platform handles network, you just write single code base and you don't care how Uno platform handles it. The cool thing about Uno platform is also that you can try it out in the browser without installing anything. So you can go to this website playground.platform.uno and you can try it out yourself by writing sample code in the browser and it will automatically render on the right side. You can also switch between various nice snippets. And this allows you to very easily test out Uno platform features without committing to anything. And finally when you're ready to install it, you can go to Visual Studio, manage extensions and search for Uno platform which will give you the Uno platform solution templates and then you can build your Uno platform solution by creating a new project and choosing multi-platform app in Uno platform. So this is the end of my short talk. You can try it out yourself, go to platform.uno for any tutorials and documentation and if you want to contact me and get more information from me, you can find me on any of these social networks and on my blog. So thank you very much, have a great day and enjoy the rest of the conference.
