Get c# classes after a program is compiled

Question

I have a program that I am making for a friend and I don't want him to see the whole code, but I want him to be able to add classes that have attributes on the classes so he can add his own stuff to it, how would I be able to get classes using a compiled program and add them to the dictionary of methods to be called upon later?

Answer 1

Use MEF.

The Managed Extensibility Framework or MEF is a library for creating lightweight, extensible applications. It allows application developers to discover and use extensions with no configuration required. It also lets extension developers easily encapsulate code and avoid fragile hard dependencies. MEF not only allows extensions to be reused within applications, but across applications as well.
