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

[Mattias Ahlenius]

Same exception even if I use the 2.7.2.1 bins: (I support you mean 2.7..
and not 2.5..)

Message: Failed to load language 'IronPython 2.7.2.1': The type initializer
for 'IronPython.Modules.SysModule' threw an exception.

InnerException:

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