The XamlReader is loading Xaml using types defined within the local assembly and the WPF assemblies without any problems.
If I include types defined within external assemblies then a XamlParseException with the following message is thrown.
Cannot create unknown type '{clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Charting}SeriesMapping'.' Line number '13' and line position '18'.
Is it possible to load types from external assemblies using this technique?
