Is is possible to instantiate a dll from the code rather than having to add it to the references? I have 2 groups of users that I have to accomodate and one has a DLL that I need to call and the other does not. The DLL is licensed so I can't redistribute it with my app. I want to accomodate both with one program. If I leave in the reference to the DLL then it will bomb if a user who does not have it installs the updated program that uses the DLL in the references. Any Ideas?
