I use clr.AddReferenceToFile because clr.AddReference or clr.AddReferenceByName can fail depending on whether or not Microsoft.Scripting.Silverlight.dll is signed (which can differ if you get the bits from codeplex or build them yourself from github), because you didn't give the fully-qualified assembly name.

It's strange because it executes onload of the Silverlight control, but sounds like that happens before the start script has a chance to finish. In my demo I trigger the event from a link.

Thanks Jimmy - I'll look at these changes and incorporate them back into 
the article.
