Someone asked me where they can find more information on learning the new concepts in VC++ 2005. According to the VC++ team, the best one-stop shop for VC++ 2005 info is MSDN dev center: http://msdn.microsoft.com/visualc. You'll find links to whitepapers and a couple of webcasts there.
In general, MSDN dev center (http://msdn.microsoft.com/developercenters/) is a great place to start if you are looking for more information on language features or about any new technologies.
Newsgroups and forums (http://msdn.microsoft.com/vstudio/community/newsgroups/default.aspx) are an excellent place to post your questions, comments, suggestions or any other feedback you may want to provide. We constantly monitor these newsgroups and provide answers as quickly as possible.
Here is the link to the Class Designer newsgroup: http://communities.microsoft.com/newsgroups/default.asp?icp=whidbey&slcid=us
