We just released the latest Visual Studio 2008 SDK online.  The latest version can be downloaded here.

The updates we’re providing with the SDK since our RTM release include:

 

·         Significant reduction in size for Visual Studio Shell redistributable packages. The Visual Studio Shell Isolated and Visual Studio Shell Integrated redistributables are now approximately 150 megabytes smaller. The redistributables no longer carry the full .NET Framework 3.5 payload. However, they contain a bootstrapper that automatically downloads the .NET Framework 3.5 runtime if it is not installed on the target computer.

·         Support for progress feedback in a chained installation. The Visual Studio Shell Isolated and Visual Studio Shell Integrated redistributables can now pass installation progress back to the chaining process. This lets developers display accurate progress in their setup programs.

·         Visual Studio Shell development now supports normal user. Developing and deploying a Visual Studio Shell application no longer requires the developer to be an administrator on a Windows XP computer or to have elevated privileges on a Windows Vista computer.

·         The SQL Server team has provided a new XML Tree Editor sample.

·         Addition documentation about the shell has been added.

Go ahead and try it out and let us know if you have any feedback.  Make sure you installed the Visual Studio 2008 Service Pack 1 Beta before installing the Beta SDK though.  More info about the Service Pack is here.
