How It Works

WPF Compatibility

We enable WPF apps to run on macOS and Linux with our Fork of WPF, which allows us to maintain API compatibility. Avalonia XPF replaces the low-level WPF code (MilCore) with Avalonia UI.

3rd Party Controls

Avalonia XPF supports a broad range of UI controls from the most popular control vendors. Where controls aren't compatible, we provide a range of options, including substitution.

Supported Platforms

Avalonia XPF currently supports Windows, macOS and Linux (desktop and embedded). WebAssembly, iOS and Android support is coming in 2024.


Licenses are available to purchase on a per-app, per-platform basis, with no limits on distribution. We also offer bespoke license agreements for more complex scenarios.
