• Multiple Instances of a single MEF DLL

  - by Travyguy9

  Apparently .NET 4.0 does not have the PartCreator/ExportFactory for non-SL. Which is something I think I need for this. I was wondering if someone can help me (with an example please) of how to create multiple instances of the EXPORTED type in a DLL. Basically say I have a DLL that contains a type ConsoleLogger and it uses the interface ILogger (which I import/export through MEF)...How would I create an instance of ConsoleLogger whenever I wanted to? Also..Is this even possible?
