CNET has an interesting teaser article describing a "black box" feature for VS2010. As a developer/tester, I can tell you this would be excellent! Imagine having all the details of the application state on a crash or error. As the article describes, it should reduce the "works fine on my box" approach to defect resolution. As a developer, it will reduce my feeling of helplessness when a defect pops up that I can't reproduce. As a tester, I will be able to provide additional information about the problem that will allow better communication between me and the developer. Apparently, there's not much more being said about VS2010 at present, but this feature alone sounds most excellent.
