Viv,

thanks for all your help. I seem to have got past the problem now (I added some more functionality into my Members.Library and rebuilt the solution and the problem went away, go figure).

I'm off until the new year so may not get back to this until then.

Merry Christmas and enjoy the festivities.

>>>No. If you are using the xmlns alias it should be a colon (so I just realized I was wrong in suggesting the correction I did).

x:Type Members:MembershipTypes

>I've no idea whether this may affect anything but I see that you have a private default constructor for the class which means it cannot be instantiated directly - but the XAML may try to do this. What happens if you make that constructor public (as a test)
