.NET Community Toolkit is a collection of helpers and APIs that work for all .NET developers and are agnostic of any specific UI platform. The toolkit is maintained and published by Microsoft, and part of the .NET Foundation.

This repository contains several .NET libraries (originally developed as part of theWindows Community Toolkit) that can be used both by application developers (regardless on the specific UI framework in use, they work everywhere!) and library authors. These libraries are also being used internally at Microsoft to power many of our first party apps (such as the new Microsoft Store) and constantly improved by listening to feedbacks from other teams, external partners and other developers from the community. Here's a quick breakdown of the various components you'll find in this repository:

Package	Latest stable	Latest Preview	Description
CommunityToolkit.Common			A set of helper APIs shared with otherCommunityToolkit libraries.
CommunityToolkit.Diagnostics			A set of helper APIs (specifically,Guard andThrowHelper) that can be used for cleaner, more efficient and less error-prone argument validation and error checking.
CommunityToolkit.HighPerformance			A collection of helpers for working in high-performance scenarios. It includes APIs such aspooled buffer helpers, a faststring pool type, a 2D variant ofMemory<T> andSpan<T> (Memory2D<T> andSpan2D<T>) also supporting discontiguous regions, helpers for bit shift operations (such asBitHelper, also used inPaint.NET), and more.
CommunityToolkit.Mvvm (aka MVVM Toolkit)			A fast, modular, platform-agnostic MVVM library, which is the official successor ofMvvmLight. It's used extensively in the Microsoft Store and other first party apps.The sample app repository is here.

All documentation for the toolkit is hosted onMicrosoft Docs.

All API documentation can be found at the.NET API Browser.
