Welcome to the MEF community site

Programming Guide is being updated right now to reflect latest release

The Managed Extensibility Framework (MEF) is a new library in .NET that enables greater reuse of applications and components. Using MEF, .NET applications can make the shift from being statically compiled to dynamically composed. If you are building extensible applications, extensible frameworks and application extensions, then MEF is for you.

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.
