WinUI

The modern native UI platform of Windows.


Explore the advantages of our platform.

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

WinUI offers a state-of-the-art UI framework for all Windows apps across both Win32 and UWP.

It provides a way to gradually migrate existing apps written in familiar technologies like MFC, WinForms, and WPF, allowing you to move these applications forward at your own pace. It also supports familiar languages spanning C++, C#, Visual Basic, and even Javascript via React Native for Windows.

Find your path forward.


WinUI can interoperate with Desktop and UWP apps to bring the most modern controls and experiences right into your app.

Which path is right for you?
