The collaboration between Microsoft and the Uno Platform is set to strengthen cross-platform .NET development, particularly through shared work on SkiaSharp, a core 2D graphics library. Uno has long focused on enabling .NET applications to run seamlessly across devices, and by co-maintaining SkiaSharp with Microsoft, the framework will gain more stability, faster updates, and better alignment with modern .NET UI requirements.
SkiaSharp itself is a .NET binding for Google’s Skia graphics library, providing developers with a portable and performant 2D rendering engine. It supports multiple platforms, including Windows, macOS, Linux, Android, and iOS, making it an ideal choice for cross-device applications. While most developers interact with SkiaSharp indirectly through frameworks like MAUI or Uno, understanding its capabilities allows for custom graphics, specialized controls, and high-performance rendering beyond standard UI elements.
Using SkiaSharp in .NET is straightforward once set up. Developers start by creating a canvas, which acts as a drawing surface, and then use paint objects to render shapes, lines, text, or images. The library includes support for anti-aliasing, transformations, and layering effects such as color filters, shaders, and alpha masks. These features allow for sophisticated graphics, animations, and custom visualizations that can be scaled and rotated as needed for different devices and resolutions.
For developers targeting Linux or less common platforms, SkiaSharp provides flexibility through community and official packages, ensuring the library works across distributions. Advanced users can even compile custom builds using the Ninja build system to optimize for specific environments. By integrating SkiaSharp into .NET projects, developers gain a low-level, cross-platform graphics engine that complements higher-level frameworks, enabling richer and more adaptable application UIs.
