Error building Player because scripts had compiler errors

Just a stab in the dark, but do you have a class named GetTypes too?

Did you ever solve it? I get a very similar issue from adding a .net 3.5 utility library to unity which only references system. I use extension methods so i cannot try it on .net 2.0 but it should work on 3.5.

$$anonymous$$y error:

Internal compiler error. See the console log for more information. output was: Unhandled Exception: System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded.

Solved for me. Turned out it was the first dll i added that was at fault. Confusingly, it only triggered the error when i added the second.
