Welcome to the MEF community site

Application requirements change frequently and software is constantly evolving. As a result, such applications often become monolithic making it difficult to add new functionality. The Managed Extensibility Framework (MEF) is a new library in .NET Framework 4 and Silverlight 4 that addresses this problem by simplifying the design of extensible applications and components.

MEF has shipped in .NET 4 and Silverlight 4!

Disclaimer: This CodePlex project gives you access to the code that the MEF team is working on for future releases. The source available on this site does not necessarily reflect what will be available in future versions of .NET or Silverlight or other platform. This is, however, a great opportunity to hear from you! We welcome any feedback you have on your experience.
