The OpenSilver 2.1 platform is available, continuing the evolution of Silverlight technology

[or1k]

The project allows to create interactive web applications using C#, F#, XAML and .NET technologies. Silverlight applications compiled with OpenSilver can run in any desktop and mobile browsers with WebAssembly support, but compilation is still only possible in Windows using Visual Studio environment.

In its current form, OpenSilver has already gone beyond a layer to extend the life of Silverlight and can be considered as an independent platform for creating new applications. For example, the project develops a development environment (an addition to Visual Studio), provides support for new versions of the C# language and the .NET platform, and provides compatibility with JavaScript libraries.

OpenSilver uses the code of the open source projects Mono (mono-wasm) and Microsoft Blazor (part of ASP.NET Core) as a basis, and compilation of applications into WebAssembly intermediate code is used for execution in the browser.
