@pter:Good question? It is generally not a great idea to pass the entity model directly to the view for binding but as always it depends on the situation. In very simple cases there is no benefit to introducing extra layers of separation.
I don't have a problem with using the context directly in the controller for doing simple queries but there are a number of patterns that promote a better separation of concerns. We will keep evolving this example over a number of episodes to show some different options.
