Answer 1

MSDN - InvalidProgramException

Excerpt:

The exception that is thrown when a program contains invalid Microsoft intermediate language (MSIL) or metadata. Generally this indicates a bug in the compiler that generated the program.

This is happening as you step through the code because as your method is called it is being JIT compiled. If the compilation by the JITer is invalid, this exception will be thrown at this point.

Answer 2

Try following-

1) Delete temporary asp.net files from C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
2) Recompile the assemblies and update the corresponding referenses
