What do people build with it?

USE CASE 1

Add clean argument validation to your .NET functions so errors are caught and reported clearly without boilerplate.

USE CASE 2

Use the high-performance package to work with memory buffers and object pools without unnecessary allocations.

USE CASE 3

Organize a desktop or mobile .NET app with the MVVM Toolkit, keeping data logic cleanly separated from the UI.

USE CASE 4

Drop in any individual toolkit package without installing the whole suite, each package works independently.

In plain English

This repository is the home of the .NET Community Toolkit, a set of code libraries published and maintained by Microsoft for developers who build software using the .NET platform. The toolkit works across all .NET application types, whether you are building desktop apps, mobile apps, or web services, and it does not depend on any specific visual interface framework. The toolkit is made up of several independent packages that developers can add to their projects depending on what they need. One package provides helper tools for checking function arguments and reporting errors in a cleaner way. Another is aimed at high-performance situations where memory usage and speed matter, offering utilities for working with buffers, pools, and two-dimensional data structures. A third package is an MVVM library, which is a way of organizing application code so that the data layer and the visual layer stay cleanly separated. The MVVM Toolkit is used inside products like the Microsoft Store. All the packages are distributed through NuGet, the standard way .NET developers share and install reusable code libraries. You can find them by searching the package names in Visual Studio or any compatible tool. Documentation for each package lives on Microsoft's official developer documentation site, not inside this repository. The project is part of the .NET Foundation, an independent organization that stewards open-source .NET projects. Contributions from outside Microsoft are welcome, and the project maintains a public roadmap through GitHub milestones so anyone can follow what is planned for upcoming versions.
