Steve Smith published two cool articles on the ASPAlliance site last week that show how to get more out of Visual Studio and Visual Web Developer. You can read them both here:
If you are looking for a good book that shows you how to get even more out of Visual Studio 2005, I'd recommend you also check out James Avery's Visual Studio Hacks: Tips & Tricks for Turbocharging the IDE. It has 4.5 (out of 5) stars on Amazon with 21 comments (always a very good sign for a book), and is packed with useful tips/tricks to get the most out of VS. You can read 5 of the book's tips/tricks online for free on the O'Reilly web-site here, and learn more about the book on its web-site here.
Hope this helps,
Scott
