Uno Platform Documentation

Uno Platform is an open-source .NET platform for building single codebase native mobile, web, desktop, and embedded apps quickly.

High level architecture

Uno Platform's application API is compatible with Microsoft's WinUI 3 API and the older UWP application API. In fact, when your application runs on Windows, it's just an ordinary WinUI 3 (or UWP) application.

This means that existing WinUI or UWP code is compatible with Uno Platform. Existing WinUI or UWP 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 rests upon the native UI framework on most target platforms, making it easy to integrate native views and tap into native platform features.
