Installed Web Tools 2013.1 on VS Express 2012 for Web, project compiles/runs but Scaffolding missing

I'm using VS Express 2012 for Web and upgraded to MVC5, EF6.1beta, and installed Web Tools 2013.1 for VS2012 Express. I reviewed and followed two or three posts to verify that all references and necessary packages were the right version and in place then cross checked that against a couple of other posts.  My project compiles and runs with out hitch, however, I don't have access to any of the new functions from the web tools. In particular I don't seem to have the option to create and MVC5 controllers through Scaffolding. The release notes indicate this should be available by drilling down through the Controllers context menu. Any ideas on what I might be missing? Despite info to the contrary, is this only avialable in VS2013 flavors?
