I tried to add a wmp to XAML via WindowsFormsHost and when compiling,
i got an error message telling that "Grid has an invalid child". I did
use the namespaces etc. The same error occurs with the exemple
included in the windows vista sdk (HostingWfInWpf) !!! Is it a kind of
a bug ? I know this can be achieved in C#, but i want it done in

Thanks for any help !
