WinUI

WinUI (Windows UI Library) is a native user interface framework for building modern Windows desktop applications, including Win32, .NET, and UWP apps. It provides a set of controls, styles, and features that align with Fluent Design System, enabling developers to create visually appealing and responsive interfaces. WinUI is decoupled from the Windows OS, allowing for faster updates and compatibility across different Windows versions.

Also known as: Windows UI Library, WinUI 3, WinUI 2, Microsoft WinUI, WinUI Framework

Why learn WinUI?

Developers should learn WinUI when building Windows desktop applications that require a modern, native UI with access to the latest Windows features and design principles. It is particularly useful for projects targeting Windows 10 and 11, where consistency with the operating system's look and feel is important, such as in productivity tools, enterprise software, or consumer apps. WinUI also integrates well with other Microsoft technologies like .NET and C++, making it a strong choice for developers in the Windows ecosystem.
