In preparing for the 2011 Arctic SharePoint Challenge next week with my awesome Puzzlepart team, we're installing the SharePoint Software Factory (SPSF) tooling available at CodePlex. There is a nice prerequisite installer that helps you download and install the Guidance Automation Extensions and Toolkit, but it would not install the guidance packages properly on my Visual Studio 2010 SP1.
Installing GAT2010.vsix failed with missing "Visual Studio 2010 SDK", so I downloaded that and got the "you must have Visual Studio 2010 installed" error instead. As it turns out, you will of course need "Visual Studio 2010 SP1 SDK" (download).
Now I've got the SPSF project types in the Guidance Packages section of File > New Project and are ready for #ASC2011.
