In his post about the opening keynote at TechEd, Ryan Gregg observes:
“Visual Studio 2005 Team System looks like a very useful integration that will probably upset a lot of third party vendors.”
It's quite the contrary, Ryan. I think Team System is going to create a wealth of opportunities for third party vendors to create all sorts of tools. I expect an explosion of third-party tools similar to the explosion of third-party controls that occured when Visual Basic arrived on the scene. Please take a look at the extensibility white paper that Allen Clark wrote. It covers the various ways that third party vendors can build on Team System.
