🧰 .NET Community Toolkit

.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.

👀 What does this repo contain?

This repository contains several .NET libraries (originally developed as part of the Windows 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 other CommunityToolkit libraries.
CommunityToolkit.Diagnostics			A set of helper APIs (specifically, Guard and ThrowHelper) 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 as pooled buffer helpers, a fast string pool type, a 2D variant of Memory<T> and Span<T> (Memory2D<T> and Span2D<T>) also supporting discontiguous regions, helpers for bit shift operations (such as BitHelper, also used in Paint.NET), and more.
CommunityToolkit.Mvvm (aka MVVM Toolkit)			A fast, modular, platform-agnostic MVVM library, which is the official successor of MvvmLight. It’s used extensively in the Microsoft Store and other first party apps. The sample app repository is here.
