What is the Uno Platform

The Uno Platform (Pronounced 'Oono' or 'Ouno') is a Universal Windows Platform Bridge that allows UWP-based code (C# and XAML) to run on iOS, Android, macOS, WebAssembly, Linux and Windows 7. It provides the full definitions of the UWP Windows 10 2004 (19041), and the implementation of a growing number of parts of the UWP API, such as Windows.UI.Xaml, to enable UWP and WinUI applications to run on these platforms.

Use the UWP/WinUI tooling from Windows in Visual Studio, such as XAML Hot Reload and C# Edit and Continue, build your application as much as possible on Windows, then validate that your application runs on iOS, Android, macOS and WebAssembly.
