I think most of us suspected it, but Visual Studio 2008 SP1 was released today which gives us the wonderful Dynamic Data and ADO.NET Data Services! I have these running already in production which always has me a little nervous when still in CTP, but now I can get my websites to RTM. And, of course, don't forget to Download SQL Server 2008 and Download SQL Server 2008 Feature Pack.
You can download Visual Studio 2008 SP1 here.
You can download the .NET Framework 3.5 SP1 here.
