Be aware that installing the November 2010 Windows Azure SDK v1.3 will break support for cloud projects running under Visual Studio 2008. To the best of my knowledge this was not widely announced (in fact, I learned about this fact during installation of the SDK). If you have Visual Studio 2008 Windows Azure projects, you’ll want to ensure that you have Visual Studio 2010 and a plan for migrating your projects prior to installing this new SDK.
When running the SDK setup on a machine with Visual Studio 2008 installed, you’ll receive a warning that “Setup has detected that Windows Azure Tools for Visual Studio 2008 is installed. As Windows Azure Tools 1.3 does not support Visual Studio 2008, if you continue to install this software, Windows Azure Tools for Visual Studio 2008 will stop working due to incompatible Windows Azure SDK version. Do you want to continue?”
