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 both API and binary compatibility with WPF. Avalonia XPF replaces the low-level WPF code (MilCore) with Avalonia.

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 basis, with no limits on distribution. We also offer bespoke license agreements for more complex scenarios.

This development marks a significant milestone, heralding a new era of versatility and accessibility for WPF developers committed to broadening the reach of their software. With Avalonia XPF, the dream of genuinely cross-platform WPF applications has become a reality.

WPF for Linux

The rise of desktop Linux in scientific computing and its significant growth into embedded scenarios makes it an excellent moment to guarantee your WPF applications are Linux-compatible. Avalonia XPF is your gateway to effortlessly cater to an extensive array of Linux distributions, requiring minimal to no modifications of your code!

Avalonia XPF can bring about significant cost savings, particularly for embedded devices. Avalonia XPF enables shifting to more cost-effective ARM-based hardware, presenting a financially savvy alternative to x86-based devices. Combined with Linux's absence of OS licensing fees, it starkly contrasts the embedded Windows ecosystem, offering a compelling financial reason to adopt Avalonia XPF.

Still have unanswered questions and need to get in touch?

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. Enterprise licenses are perpetual, with optional upgrades after one year, while Indie licenses are subscription-based. There are no limitations to distribution or the number of developers developing the app.

Apps built with XPF remain fully functional, even if your license expires. Enterprise licenses are perpetual, allowing you to continue building with the last XPF version active during your subscription (generous renewal discounts available). Indie licenses operate on a subscription model, requiring an active subscription for ongoing XPF development.

No. Our Indie subscription requires a commitment of a minimum of 12 months. However, after this initial period, you have the flexibility to cancel your subscription at any time.
