Avalonia is an open‑source, cross‑platform UI framework for .NET that lets you build desktop, mobile and WebAssembly applications with C# and XAML. It provides its own rendering engine and a rich control library, enabling pixel‑identical UI on all supported platforms.
Use cases
- build a native desktop app for Windows, macOS and Linux using C# and XAML
- create a cross‑platform mobile app for iOS and Android with a single codebase
- port an existing WPF application to run on macOS and Linux without rewriting UI
- develop a WebAssembly UI that runs in the browser using the same Avalonia code
- design a MVVM‑based application with a rich set of stylable controls
When to choose
- you need a single .NET UI framework that targets desktop, mobile and WebAssembly
- your team is familiar with XAML and MVVM patterns from WPF or UWP
- you want pixel‑perfect rendering across platforms without native control wrappers
- you prefer an MIT‑licensed, actively maintained open‑source solution
When to avoid
- you require deep integration with native platform UI controls that Avalonia does not expose
- your project depends on a specific platform‑only UI toolkit (e.g., WinForms, UIKit)
- you need a framework with built‑in designer tools comparable to Visual Studio's WinForms designer
