How to add my own menu in VS2012?

Hi,

I've managed to create a command (just trying to add "ToUpper" on a selection) and placed it in an existing menu (e.g. "Edit"). This Works, but how can I create my own menu - for example next to "Edit"? I've tried to add a new temporary CommandBar but it is never visible (yes, it is set as visible). Some example (pref C#) would be great!
