I'm working on my TechEd demos which includes DB Projs and MSBuild + Team Build .I needed to remove one of my build agents.
To remove a build agent, navigate to to the Build Menu, or the Build Explorer. Click on Manage Build Agents in order to remove/edit/add a build agent.
In order to use the Build Menu, you must first open the Team Explorer. Otherwise, the Manage Build Agents will not be part of the menu.
