>Hi,
>Simple piece of XAML referencing a component in another assembly:

>        </ContentControl>
></UserControl>

The assembly that this is in has a reference to the project for the 'Canvas' assembly. When this runs I get the following exception:

That is weird... Have you tried adding a reference to 'Canvas' into what ever assembly is calling "LLNet.Modules.Library.Views.Test"?

not sure if it applies, but this is why I ask:
