Previously, in VS 2010 Professsional, in the Server Explorer, you could connect to your database and you would see a Database Diagrams folder listed under your database.
I'm now on VS 2012 Professional, and the Database Diagrams folder is no longer there; nor can I add it when I right click on the database.
Also, I cannot find it in the new SQL Server Object Explorer window within VS 2012.
Any idea, where it is now?
