Avalonia XPF is based on WPF shipped with .NET 6.0 SDK. For WPF apps that are using older versions of .NET, we recommend upgrading to .NET 6 or .NET 7.
We're working hard to enable almost all of the WPF APIs. Currently, unsupported WPF features include Visual3D, Viewport3D, InkCanvas, Win32 interop, and custom Window chromes.
Yes. Libraries that don't use any Win32 APIs typically work without modification. For libraries that use Win32 APIs, we enable a subset of Win32 APIs to work across supported platforms.

Yes, you can use Avalonia XPF for open-source projects. However, it's essential to keep your unique license key private. Your license key is directly tied to your XPF subscription, and sharing it publically could allow unauthorised use of your benefits. We recommend that OSS maintainers consider modernising their projects with Avalonia UI to enable wider adoption and community engagement.
Avalonia XPF is licensed per app and enables building for Windows, macOS and Linux. There are no limitations to distribution of the app or how many end-users your app can have. Each license includes a perpetual license, assuring our users that they will always have access to a specific version of Avalonia XPF. The license includes 12 months of support and updates from the date of purchase. During this period, users have access to all new versions and features released for Avalonia XPF. The latest build available on the last day of the support period becomes the user's perpetually licensed version, which they can continue to use and distribute indefinitely. This approach ensures that users have permanent access to Avalonia XPF, even if they opt not to renew their license.
Apps built with XPF remain fully functional, regardless of the tier purchased, even if your license expires. Licenses are granted as perpetual licenses, enabling you to always build with XPF.
For Business and Enterprise licenses, the optional second-year renewal is 50% of the first-year cost. We are committed to continually reducing the cost of XPF renewals year over year.
