In EF 5 we inadvertently had the DbContext template moved to the Data category while the EntityObject and Self-Tracking Entities templates available in the gallery belong in the Code category. As far as I remember all the templates went in the Code section before, and in fact the EF 4.x version of the DbContext template we have in the gallery still belongs to Code.
I don't think this is something we need to fix for EF5 because it is just a small usability hindrance, but we should keep it in mind for EF6.
