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.

Licensing

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.

WPF for macOS

For years, developers have voiced their desire to run WPF applications on macOS. Avalonia XPF empowers developers to bring their WPF applications to the macOS platform with minimal changes required, ensuring that your WPF applications can now enjoy a wider audience.

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.

LINQPad on macOS

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.

FAQ

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. Avalonia XPF comes with both documentation and the Business, and Enterprise tier comes with email support. Our engineers will also be available to work with your team to ensure your apps run perfectly.

XPF Indie is intended for individuals, but companies with an annual revenue under €500,000, fewer than 3 employees, and who have received less than €1m in capital investment are eligible for Indie licenses. For consultants, you can develop applications for clients using an XPF Indie license if you retain ownership of the intellectual property (IP) and your client uses the application internally without redistributing or white-labelling it. If your client owns the IP or intends to redistribute the application, they must qualify for and obtain their own XPF Indie license. Contact us to confirm your client's eligibility. Note that XPF Indie allows limited client use with specific conditions.

No. Avalonia XPF is not open-source, and its source code is not freely available.

Yes. Avalonia XPF Works with all WPF applications, regardless of the language used. We have tested applications developed with C#, VB.NET and F#.

Avalonia UI will stay free and open-source, continuing to see new features and many updates. Avalonia XPF is a premium product designed for businesses, with the revenue going towards funding the development of our OSS projects, including Avalonia UI.

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. Business and Enterprise licenses are granted as perpetual licenses, enabling you to always build with XPF. Indie operates on a subscription model and requires an active subscription for ongoing XPF development, but built apps will work forever.

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.

While we don't offer a free trial, we stand behind Indie XPF with a comprehensive 30-day money-back guarantee. This means you can test all features risk-free and get a full refund if the software doesn't meet your needs. We believe this gives you the best of both worlds: immediate access to the full version and complete peace of mind with your purchase.
