The Windows Community Toolkit is a collection of reusable UI controls, helper functions, and app services designed to accelerate development for Universal Windows Platform (UWP) applications on Windows 10. It provides a library of XAML-based controls and components that handle common interaction patterns, enabling developers to build apps that run across PC, Mobile, Xbox, IoT, and HoloLens devices with consistent adaptive layouts.
The toolkit is distributed as NuGet packages for straightforward integration into .NET projects, and it includes a companion sample app that demonstrates control behaviors and interaction patterns for rapid prototyping. Helper functions reduce boilerplate code for typical development workflows, while Visual Studio tooling integration streamlines setup and usage.
The toolkit covers Windows 10 UI development with reusable controls, cross-device adaptive layouts, and app services for notifications and connectivity. It also provides utility functions and extensions for simplifying common XAML development tasks.
