• kalinkula TypeProvider.RemoveAssembly

  Does TypeProvider.RemoveAssembly somehow actually unload the assembly from the app domain (I didn't that's possible) The real issue is if we have a running implementation where someone decides to change the logic in a code activity.

  I am confused as to when the Parent property will be non-null. Based on the compositional model, I would have expected it to give me a reference to my container activity any time my activity is living inside a composite activity, but that doesn't appear to be the case.
