I've got a brand new shiny team foundation server installation. I've created a team project. I have an existing solution that I want to now add to that team project. How do I do it?

The old File|Source Control|Change Source Control... menu option isn't there anymore.

I also expected to find something along the lines of Project|Add To Source Control..., but there's no option anything like that either.

Under the File menu, I have two different Source Control menus, each with a single option:

The first has "Migrate code analysis policy settings to solution". Choosing that option does nothing at all, near as I can tell.

The second has "Workspaces...", and choosing that brings up the workspaces manager as I'd expect.

So what's up? I'd really rather not create the projects again from scratch and copy all the existing files into them...
