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.
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.
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.
Future-proof your app with WinUI. With 1 billion devices running Windows 10, and Windows 11 recently announced, WinUI continually expands to meet the needs of every modern device. Many of Microsoft's own most-used industry applications already use WinUI today.
WinUI offers a state-of-the-art UI framework for all Windows apps across both desktop (Win32) and UWP.
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.
