Avalonia is a free and open-source .NET cross-platform XAML-based UI framework inspired by WPF/UWP and distributed under the MIT License. Avalonia supports the MVVM pattern.
It enables development of cross-platform applications using any .NET language, including C#, F# and VB.NET for Windows, Linux, macOS, iOS, Android and WebAssembly.
Avalonia supports multiple renderers, including Direct2D and Skia Graphics Engine, allowing it to operate on a broad range of platforms. Avalonia draws its entire UI, mirroring the approach taken by Flutter.
