So what is "Team Foundation" anyway?
"It is the server-based part of Team System that ties together many of the various pieces of the software development lifecycle. It provides a suite of source control, work item tracking, Excel and Project integration, reporting, project portal, and build automation functionality for seamless and effective management of a team-driven development project."
