One of many improvements made to Visual Studio 2008 Service Pack 1 is that VS 2008 SP1 Beta customers will not need to uninstall SP1 Beta before installing the release of SP1. The same is true for Visual Studio 2008 Express products and .NET 3.5 SP1 – both of which are complete upgrades to older products that may already be on the system or that can be installed on a clean system.

So please read the requirements and known issues, give Visual Studio 2008 SP1 Beta a try, and provide feedback about we can improve the release of VS2008 SP1 and future releases.
