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 4.0 that addresses this problem by simplifying the design of extensible applications and components.


Disclaimer: MEF is in development. The source available on this site, does not reflect the final state of the product, it is a preview of what will be shipping in the framework in the future. We welcome any feedback you have on your experience.
