I would like to do some server-side manipulation of RadDocuments created in Silverlight (remove header and footer specifically). I have a standard .net assembly referencing the Telerik.Windows.Documents assemblies from the WPF Q3. I get an exception on Export. Am I doing something wrong - or is this simply unsupported? This same code works fine in SL.

var docs = EntityManager.FindEntities(EntityState.Added | EntityState.Modified).OfType<Document>();
			docs.ForEach(
				d =>
					{
						var provider = new XamlFormatProvider();
						var radDocument = provider.Import(d.Content);
						radDocument.Sections.First.Headers.Default = new Header();
						radDocument.Sections.First.Footers.Default = new Footer();
						d.Content = provider.Export(radDocument);
					});

_message "The type initializer for 'Telerik.Windows.Documents.Layout.RadTextMeasurerSL' threw an exception."
+ _innerException {"The calling thread must be STA, because many UI components require this."} System.Exception {System.InvalidOperationException}
