Cross-Platform Solutions: WPF4Linux WPF Developer Library

2025

High-performance rendering and advanced Windows compatibility

"Cross-platform solutions" summed up the results of an important stage in the development of their product - WPF4Linux. From April to October 2025, the library was dramatically updated, turning from a tool for migrating WPF applications into a full-fledged WPF development platform. This allows client companies not only to migrate existing solutions, but also to further develop for Windows, Linux and macOS from a single code base, preserving a common technology stack and strategically protecting investments in the.NET and WPF ecosystem. The company announced this on November 17, 2025.

Over the past six months, the WPF4Linux has received a series of large-scale improvements that have enhanced performance, compatibility and ease of development:

• High-performance rendering. The redesigned graphics engine with support for OpenGL and Vulkan provides multiple rendering acceleration in both Linux and macOS.
• Maintain up-to-date standards. The platform was one of the first on the market to implement full compatibility with the current versions of.NET 8 and.NET 9, which allows you to use the capabilities of the framework without restrictions.
• Enhanced Windows compatibility. Enhanced API layers emulate the behavior of standard Windows dialogs (including WinForms MessageBox), ensuring that complex interfaces work correctly without rewriting UI logic.

WPF4Linux is becoming a strategic tool for digital transformation of enterprises using the.NET stack. The updated version forms the basis for the long-term development of corporate and industrial applications, combining the worlds of Windows, Linux and macOS into a single development ecosystem. In the coming year, the company plans to expand support for native integrations with macOS graphics subsystems and implement accelerated packaging and application delivery tools.

macOS support

Cross-Platform Solutions announced support for macOS in the WPF4Linux library on September 10, 2025. A single code for Windows, Linux and macOS opens up new multi-platform development opportunities for enterprises using the WPF (Windows Presentation Framework).

Using WPF4Linux, WPF developers can migrate custom Windows applications to Linux and macOS without code changes, reducing the time to adapt to new platforms from a few months to a few days or even hours. And in the future, in the already familiar workplace, to implement end-to-end cross-platform development for all three of the most popular desktop operating systems: Windows, Linux and macOS.

macOS and WPF4Linux libraries are available to users:

Optimized memory consumption and fast start of WPF applications. Starting packets takes less than a second, memory consumption is optimized. This allows you to fully use the entire fleet of devices and operating systems available at the enterprise: from Windows to Linux and macOS;

Almost zero adaptation of WPF code and binary compatibility. Generated code can be executed on Apple Silicon platforms (processors M1, M2 and higher) and Intel via NativeAOT 6;

Native performance and application rendering. Hardware acceleration provides smooth animation on Retina screens and minimal use of processor resources.

Compilation and assembly of applications for all three operating systems is carried out in an environment familiar to programmers, while preserving the existing developments and popular vendor libraries such as Telerik, DevExpress, Syncfusion, SciChart, etc.

All this ensures a fundamental reduction in migration costs. The per-app license allows you to install user applications on an unlimited number of workplaces, in organizations of any size. It is enough for developers to rebuild the solution for macOS/Linux: business logic and interface remain almost unchanged, as does the user interface.

The developer noted that the use of WPF4Linux will allow all corporate users of WPF applications to mitigate the risks associated with the problems of TPM locks of Windows 11 and the end of support for Windows 10 from October 2025. According to our estimates, from 40 to 60% of Russian corporate applications are developed using the Windows Presentation Framework - WPF.
