I think the way to do this might be some kind of cus...

But this doesn't seem to be working? I would imagine that it would throw an exception if I entered, e.g., "aaaa" as a URI. Thus, triggering my current setup, which is su...

I want my WPF ComboBox's ItemsSource property to be bound to MyListObject's MyList property. The problem is that when I update the MyList property in code, the WPF ComboBox is not reflecting the update. I am raising the PropertyChanged event after I perform the update, and I thought WPF was supposed to automatically respond by updating...

I would like to provide ...
