Using C#, XAML + Uno Platform to Build One Codebase, Cross-Platform Apps

For more than a decade, we have been developing applications with C# and XAML. Throughout that time, the pair has really only been known for Desktop (WPF) and UWP applications.

Later came Xamarin, which utilizes C# as a unified language to share between all platforms. Then Xamarin.Forms was introduced, which was different in that it utilized XAML to develop the user interface with a single codebase for cross-platform (iOS, Android, UWP).

This progression has excited all the WPF developers out there. The only remaining platform left was web development. At one time, Silverlight was the option, but it was deprecated because of heavy loading and security concerns of browser plug-in solutions.

Then came the WebAssembly [also known as Web Assembly Modules (WASM)] that web browsers can directly execute without having to parse a source file.

In this post, we will discuss how to create a rich user browser interface using the cross-platform Uno Platform and WebAssembly technology. The example application will walk through building Models, ViewModel and View under a shared project that is common to all different platform-specific projects.
