If you are a developer using Visual Studio 2008 and have tried to install SQL Server 2008 on top of it, you might have noticed that it doesn’t want to install. According to KB956139 Visual Studio 2008 Service Pack 1 is a required if you intend to use certain features like the the SQL Server Management Studio.
The good news is that Visual Studio 2008 Service Pack 1 has been released to MSDN. It weighs in at a hefty 831MB so hopefully it will have lots of cool stuff and performance improvements not to mention support for the .NET Framework 3.5 Service Pack 1 release that has already shipped as part of SQL Server 2008.
