This week we released the Visual Studio 2010 SharePoint Power Tools. This fills a gap that has often been a room gasp when I talk to developers. I'd spend some time telling them all the benefits of Sandboxed Solutions only to then tell them that they could use it if they wanted to develop using the Visual Web Part template. This little guy here solves that problem. Enjoy!
