In my last post I addressed regions in the Composite Application Library for WPF/Silverlight (Prism). I looked at what they were and how they were used. But by the end of the post I felt that the concept of View Injection needed further attention. I’ve almost exclusively used View Discovery up to this point in my development. But when I’ve run into a need to use View Injection I’m uncomfortable with what seems to be a tightly coupled relationship.
