Odd, VB or C#? On build with C# I get :
Unknown build error, ' 'clr-namespace:Whatever; assembly=Junk' mapping URI is not valid. Line 3 Position 9.'
Also, stupidly enough, if I remove the assembly reference from the project the compiler is smart enough to flag up an additional error: "Assembly 'Junk' was not found" which implies that it *does* know we're looking for that assembly in the XAML after all :-{
That said, and although I feel your pain, I must say I've probably added hundreds of xmlns: attributes without hitting that problem - but I'm the lazy type who waits for the dropdown to be sure I'm selecting the right namespace....

>>>Although I would have much rather been at the beachfront bonfire party with my peeps, I had to get a relatively simple Silverlight 4.0 LOB project done. So I stayed home, unhappily typing XAML like this:

>>>I build the project. No errors! Great!

>>>Since my VS help doesn't work, like, AT ALL, I go to Google (which I would probably do anyway, given the relatively unhelpful ways of Microsoft Help.) However, after 10 minutes of googling I still don't find any good answers to this particular problem.
