I thought that this line meant I could refer to it as Members alone:

xmlns:Members="clr_namespace:Members.Library;assembly=Members.Library"

Maybe I'm misunderstanding what this does, but I thought it was like a using Members.Library, but giving it an alias called "Members".

Is that right?

If I use Members.Library.MembershipTypes then I get the error:

The type reference cannot find a public type named 'Members.Library.MembershipTypes'.
