Remoting between two seperate projects

If anyone else is having the error
Unhandled Exception: System.InvalidCastException: Return argument has an
invalid type.
when calling a method on a remote object that returns a complex data type
(IE not int or string), I have figured out a workaround.

When you want to share an object between two programs in general, I
recommend putting all the classes that you might need to share between the
two programs in a completely seperate DLL class library, NOT in the original
projects. Then, reference both projects to that DLL and you and the
remoting will not bug you, since it knows that the versions are truly
identical of the two classes.

My theory about this is that if you compile the same file twice it will
generate two different unique keys, and so when remoting tries to send the
object, it thinks the versions are different.
