Ambiguous assemblies / DLL

I was trying to implement URL re-writing as described in approach #3 here: http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx

I'm quite sure I know what the problem is here, but no clue how to fix it.  I know from the error and searching online that basically my app DLL is conflicting with my temp .net files DLL, but I can't seem to figure out how to clear it.


I didn't rename the class (because I don't believe I should have to do that or want to)
