The Windows UI Library (WinUI) is the official native Microsoft UI controls and features for Windows UWP apps.
Microsoft says WinUI is the easiest way to build great Fluent Design experiences for Windows. It can be used in any Windows 10 UWP XAML app, or in a Xamarin.
Microsoft has launched a new website to promote the open-source solution for developers, touting the following features:
- Modern and Seamless UIs
WinUI makes it easy to build modern, seamless UIs that feel natural to use on every Windows device. It embodies Fluent Design to enable intuitive, accessible, and powerful experiences and the latest user interface patterns.
- Unmatched Native Performance
WinUI is powered by a highly optimized C++ core that delivers blistering performance, long battery life, and responsive interactivity that professional developers demand. Its lower system utilization allows it to run on a wider range of hardware, ensuring your sophisticated workloads run with ease.
- Developers in Control
WinUI will never force you to update – you choose when to adopt a new version. Our commitment to open source development means you have a voice in the platform’s future.
- Built for Windows 10 and Windows 10X
Future-proof your app with WinUI. With 1 billion devices running Windows 10, and used in Microsoft’s own industry applications, WinUI continually expands to meet the needs of every modern device.
- The Future of Windows Development
- Works with your favorite cross-platform technologies.
With our partner platforms, you can write your app in a variety of languages and see it run as-good-as-native on Windows, other operating systems, and the web.
- Resources that empower your development experience.
With expansive documentation, videos, blog posts, and recorded monthly Community Calls where you get your questions answered, WinUI is rich with educational materials designed to empower you and your development decisions.
