David Hayden has published a helpful screencast on the new Unity Application Block. The screencast works through some Unity fundamentals and is a useful starting point for anyone interested in Dependency Injection. I was particularly interested to learn about container hierarchies, which reminds me of the work item hierarchy that is available in Smart Client Software Factory. I guess I need to delve some more into Prism and see whether container hierarchies are used.
