[IronPython] WPF module in IronPython scripting?

[Markus Schaber]

Hi, Lukáš,

It may be a problem related to the .NET assembly search path, or it may be the host application blocking/filtering the loading of arbitrary assemblies.

Did you try clr.AddReference() with the Assemblies being in the GAC?

Did you try clr.AddReferencetoFileAndPath()?

Could you try to catch the exception, and explore it for more details (e. G. an inner exception)?

Regards,
Markus
