The SQL Server Modeling team has released an update of the November CTP that works with Visual Studio 2010 RC. Kraig Brockschmidt made the announcement in the MSDN Forums earlier today.
As I reported earlier, the Visual Studio 2010 release candidate (RC) was not compatible with various other prerelease bits. That’s a good thing: trying to get all of the different teams to deliver prerelease software in lock step would slow down the development process down with little commensurate value. In other words, it is a small and reasonable price to pay for working with the technologies before they are completed.
According to Chris Sells, the new SQL Server Modeling November 2009 CTP Release 2 only updates the original November 2009 CTP so that it works with Visual Studio 2010 RC and .NET Framework 4 RC. It does not fix anything else or deliver any new functionality.
The recommended sequence, described by Kraig, is to uninstall the previous Modeling CTP, uninstall VS 2010 Beta 2, then install VS 2010 RC, then install the new Modeling CTP Release 2. If you’ve already embarked on some other path, see Kraig’s notes for details on getting order restored to the universe.
