TypeNameParserException is thrown on initialization

[grokys]

When the control is created, a TypeNameParserException is thrown with the message:

Prefix 'Controls' does not map to a namespace.

This exception is caught somewhere so the program can continue to run, but if "Break on exceptions" is enabled in Visual Studio it causes the debugger to break. It took me about 2 hours to realise that execution can continue after this exception is thrown :(

(Excellent work BTW!)
