This is a little old, but I needed to get it out.  Basically, if you want some help building applications that take advantage of Windows Vista functionality, go and look at this. 

Project codename "Glidepath" is an Evangelism initiative targeted at helping MicroISVs get started and be successful with a focus on Windows Vista.

Project Glidepath includes a free software factory add-in for Visual Studio 2005 that delivers, via RSS, guidance, content, code samples, step-by-step instructions and even custom tools that help MicroISVs take full advantage of Windows Vista including .NET 3.0 (WPF, WCF, WF, and CardSpace) as well as many non-technical aspects of being a MicroISV.

Project Glidepath also features the Windows Vista Spotlight highlighting MicroISV applications available worldwide that are compatible with Windows Vista.

Full information plus community forums and a blog are available via www.projectglidepath.net
