High level architecture

Uno Platform's application API is compatible with Microsoft's WinUI 3 API. In fact, when your application runs on Windows, it's just an ordinary WinUI 3/WinAppSDK application.

This means that existing WinUI code is compatible with Uno Platform. Existing WinUI libraries can be recompiled for use in Uno Platform applications. A number of 3rd-party libraries have been ported to Uno Platform.

Uno Platform is pixel-perfect by design, delivering consistent visuals on every platform. At the same time, it can either use the native UI framework on some target platforms or use a Skia-based rendering approach, while making it easy to integrate native views and tap into native platform features.
