Mef import all types implementing an interface specified at runtime

Question

Can i write a class to use mef to import all types implementing a specific interface and then specify this interface at run time. (i know i need to tag the implementors with export)

Example usage:

IEnumerable<IExcitingClass> excitingClasses = ClassImporter<IExcitingInterface>.ImportAllFrom(specifyDirectory);

Is this possible?

Answer 1

You can create a container using a DirectoryCatalog, and call container.GetExportedValues<IExcitingClass>. Is that what you want?
