A modern UI framework with rich controls and Fluent Design for building high-performance Windows applications.
WinUI is a modern UI framework developed by Microsoft that provides a rich set of controls and styles for building dynamic and high-performing Windows applications. It implements Fluent Design principles to create intuitive and accessible user interfaces, and is optimized for modern hardware. As part of the Windows App SDK, it enables developers to build apps that run across multiple versions of Windows.
Windows application developers using .NET with C# or C++ who want to build modern, high-performance desktop applications with a consistent Fluent Design interface.
Developers choose WinUI for its native integration with the Windows platform, comprehensive control set, and adherence to Fluent Design, ensuring their apps look and feel like modern Windows experiences. It offers performance optimizations and supports multiple architectures, making it a robust choice for building Windows apps.
