The Uno Platform is a Universal Windows Platform Bridge that allows UWP-based code (C# and XAML) to run on iOS, Android, and WebAssembly. It provides the full definitions of the UWP Windows 10 October 2018 Update (17763), and the implementation of a growing number of parts of the UWP API, such as Windows.UI.Xaml, to enable UWP applications to run on these platforms.
Use the UWP tooling from Windows in Visual Studio, such as XAML Edit and Continue and C# Edit and Continue, build your application as much as possible on Windows, then validate that your application runs on iOS, Android and WebAssembly.
Visit our documentation for more details.
