Microsoft have just release v 1.1 of the Visual Studio Extensions for WSS - VSEWSS. These work with Visual Studio 2005 and offer a few enhancements of the 1.0 release. There will be another release mid year that will add support for VS08.
WSS dev is a huge hairy beast and it can be hard to get started - or even figuring out where to start. The best part about new release is the user guide that is provided with VSEWSS. This is something that some clever chaps at Intergen have been working on. I provided some very minimal input reviewing their work which is basically providing me with some free training in exchange for fixing a few typos! The user guide will improve over the next few months as we add more sections so keep checking for updates.
