Getting the following exception when attempting to bind a python delegate to
an event handler. Has anyone come across this before?
Unhandled Exception: System.TypeInitializationException: The type
initializer for 'Python.Runtime.CodeGenerator' threw an exception. --->
System.InvalidCastException: Unable to cast object of type
'System.Reflection.Module' to type 'System.Reflection.Emit.ModuleBuilder'.

Here is a simple script that demonstrates this error
>>>>
from System.Windows.Forms import Application
def global_exception_handler(sender, event_args):
print "GOT AN EXCEPTION"
print event_args.Exception
Application.ThreadException += global_exception_handler
