The latest version of OpenSilver 2.2, a remake of Microsoft’s retired Silverlight web application framework, includes support for migrating applications created with Visual Studio LightSwitch that targeted Silverlight.
OpenSilver was launched in October 2021 by a French company, Userware. It is an open-source, MIT-licensed reimplementation of Silverlight. OpenSilver compiles .NET and XAML code into HTML5 and WebAssembly, reimplementing standard and selected third-party controls. It allows developers to reuse instead of rewriting their legacy Silverlight or XAML applications. The latest update to OpenSilver was version 2.1 in February 2024, with the support for F# language.
