WinUI Gallery is a demonstration app that showcases the controls and design system available in WinUI 3 and the Windows App SDK.
The app solves the problem of learning how to build modern Windows applications by providing interactive samples of every WinUI control alongside their markup and code-behind. Developers can see how each control works in practice, understand the Fluent Design guidelines through examples, and learn responsive design patterns by examining how the gallery itself adapts to different screen sizes and form factors.
WinUI Gallery suits developers building Windows desktop applications who want to understand the available UI controls and best practices for using them. The app is particularly valuable for those new to WinUI or the Windows App SDK, as it provides both visual demonstrations and the actual code needed to implement each control. The gallery includes design and accessibility guidance pages alongside the control samples, making it a comprehensive reference tool rather than just a showcase.
The project maintains an active backlog of improvements tracked on its project board and explicitly welcomes community contributions through pull requests and issue discussions. The team regularly updates the gallery to include the latest WinUI NuGet packages and new controls as they become available in the framework.
