.NET doesn't like having two assemblies that differ only by extension.
To the runtime TestNAnt.dll and TestNAnt.exe look exactly the same. When it
tries to resolve the type "TestNAnt.UsedClass, TestNAnt, Version=0.0.0.0,
Culture=neutral, PublicKeyToken=null" it looks to see if it has an assembly
called "TestNAnt, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null" in
memory. It finds TestNAnt.exe, and so it looks in there for
TestNAnt.UsedClass. When it doesn't find it, it throws the exception you
see.
The solution is to name your assemblies different things.
