Was watching this video and heard some cool things about new IDE development. Apparently 2010 IDE contains helpers for TDD, If you write a method that doesn’t exist, click a button and it’ll create it. Also the new debugger allows you to “step back” in history. Looking forward to 2010 Release Candidate.
