SQL Server 2008 and Visual Studio 2008
Both products contain 2008 in the name and come from the same vendor, Microsoft, so they must work together right? Well not quite Visual Studio 2008 was actually released at the end of 2007 and SQL Server 2008 is not going to be released for some time to come. So not surpisingly VS2008 doesn't quite support SQL2008 out of the box.
But fortunatly Jackie Goldstein wrote an article showing ow to do this. You can read the article here.
