Uno Platform

Uno Platform is an open source cross-platform graphical user interface that allows WinUI and Universal Windows Platform (UWP) - based code to run on iOS, macOS, Linux, Android, and WebAssembly. Uno Platform is released under the Apache 2.0 license.

Applications can be built by using the UWP tools in Visual Studio on Windows, including XAML and C# Edit and Continue, and run on iOS, Android or in WebAssembly in a web browser. A plug in for Microsoft Visual Studio is available from Microsoft's Visual Studio Marketplace. The community surrounding Uno Platform open source project comes together at its annual conference UnoConf.
