Avalonia XPF
Unleash the full potential of your existing WPF apps with our cross-platform UI framework, enabling WPF apps to run on macOS and Linux without requiring expensive and risky rewrites.
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.
Licensing
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.
Developer Experience
Experience a smooth transition to Avalonia XPF, designed to provide developers with a familiar development experience with WPF. Our innovative platform ensures enterprises can harness their existing investments in WPF, making it effortless to adapt and work on projects across macOS and Linux.
Embrace the power of Avalonia XPF and enjoy a hassle-free, unified WPF development experience across platforms.
Migration Analyser
Make informed decisions about migrating your mission-critical applications to Avalonia XPF with confidence, backed by the insights the Avalonia XPF Migration Analyser provides.
It intelligently scans your WPF application to determine compatibility with Avalonia XPF, saving you time and effort by identifying potential issues.
Licensing
Avalonia XPF is currently in preview, meaning that its pricing is subject to change. When Avalonia XPF becomes generally available, its pricing will increase.
