Cannot automate Silverlight app that calls Marshal.SizeOf

If a Silverlight 5 OOB application makes any elevated trust calls, such as Marshal.SizeOf and you try to automate it with Test Studio you will get an error like this:

System.MethodAccessException was unhandled by user code
  Message=Attempt by security transparent method 'FontDialog.FontInteropHelper.ShowFontDialog()' to access security critical method 'System.Runtime.InteropServices.Marshal.SizeOf(System.Object)' failed.

Hello,

The problem is specific to a dialog in the customer OOB application which Test Studio cannot automate. Unfortunately attaching the recorder breaks the dialog.

I'm afraid we cannot resolve the problem, at least in near future.

Regards!
