Alternately now that you've got the types in Silverlight you could display Type.AssemblyQualifiedName or Assembly.FullName.  It'd be the Silverlight strong name viewer app :).

Just worked out the 'sn.exe' path myself. The following seems to work:


import clr
clr.AddReference('System.Windows.Controls, Version=1.0.0.0, 
Culture=neutral, PublicKeyToken=31bf3856ad364e35')


Great!!
