Visual Studio 2010 (beta 2) can be connected to an existing TFS 2008 Server. Much of the new great stuff is then not available, quite naturally. But I was quite positively surprised that some stuff I had not expected to work in fact did. Which of course means it’s client stuff more than server stuff. Anyway, here comes:
History across branches: You can now see the history of a versioned item even it started it’s life in another branch, and even if you are connected to a TFS 2008 server.
You can see that this item started out in a Development (Feature) branch, changeset 33008, but in changeset 34502 it was merged into the Main.
