[Ironpython-users] Problem with embedding IronPython into Silverlight Application

[Mattias Ahlenius]

Thanks for your quick reply Keith,

Tried you code and I still get the same Exception:

"Attempt by security transparent method
'IronPython.Modules.SysModule.GetPrefix()' to access security critical
method 'System.Reflection.Assembly.get_Location()' failed."
