Last week I was presenting at Microsoft Campus Days in Copenhagen. During one of my presentations on Application Management using Configuration Manager 2012, I got a question on dependencies, and how to see what applications (Deployment Types) depends on a specific application, before you retire or delete an the application.
On the References tab for the application, you can see which Applications that depend on this application.
I don’t remeber who asked the question but here is the answer. 
Enjoy.
