This repo contains the Visual Studio team's implementation of .NET's managed extensibility framework.

It is broken up into several NuGet packages, as listed below.

## Microsoft.VisualStudio.Composition

[![NuGet package](https://img.shields.io/nuget/v/Microsoft.VisualStudio.Composition.svg)](https://nuget.org/packages/Microsoft.VisualStudio.Composition)

### Features

* A new, faster host for your existing MEF parts

* Reuse the MEF attributes you're already using

* `ExportFactory` support to create sub-containers with scoped lifetime (i.e. sharing boundaries)

### Documentation

* [Why VS-MEF?](doc/why.md)

* [Differences between .NET MEF, NuGet MEF and VS MEF](doc/mef_library_differences.md)
