This is actually just a limitation inside of Silverlight.  For some reason
Assembly.GetName() is a security critical method and cannot be called.  It
also fails in a simple C# Hello world app with:

Attempt by security transparent method 'SilverlightApplication1.MainPage..ctor()' to access security critical method 'System.Reflection.Assembly.GetName()' failed.

I have no clue why this limitation exists (maybe some information disclosure
issue?)  but I think you could do:

AssemblyName(assembly.FullName).Name

instead.
