Description of Problem:
An exception is thrown when instantiating a class using the generic "new T()".
Steps to reproduce the problem:
1. Load the attached project
2. Run it
Note the function "WorkAroundBugs" in Main.cs. You can uncomment those lines to
see this execute correctly.
Actual Results:
Unhandled Exception: System.MissingMethodException: Method not found: 'Default
constructor not found...ctor() of Db.User'.

Expected Results:
The object gets created and no exception is thrown. (There is an additional bug
posted regarding missing Setters, if this is patched then things work.)
How often does this happen?
Always
