MEF and singletons

Question

Hi,

I have an object with more than one interface and I want to resolve this dependancies with MEF. But its important, that the instance of the object is a singleton, so how can I tell MEF to do so?

Thanks

Gerhard

When you export your class use the creationpolicy attribute

[PartCreationPolicy(CreationPolicy.Shared)]

[Export(typeof(IMyInterface))]

public class MyClass : IMyInterface

{

}
