The Managed Extensibility Framework (MEF) is a library for creating extensible managed applications i.e. .NET applications which can be extended by plug-in components. It is part of version 4.0 of the Framework. A MEF component (or 'part') can declare both its dependencies ('imports') and its capabilities ('exports'). This allows an MEF application to discover what parts are available at runtime and means that a given part can be used not just by a single application but by multiple applications without the need for any configuration.
