NUnit, RegAsm, and "Failed to generate type library"

by

I’m trying to use COM+ to manage database transactions in my unit tests.  All of a sudden, I start getting all these weird errors saying “Failed to generate type library.“  No clue what was going on.

I ran “regasm“ over the unit test assembly and all was healed. 

Weird, huh?
