title: Why TFS does not allow multiple collections to be connected with a single same Build Controller?
body: <p>According to <a href="http://geekswithblogs.net/hinshelm/archive/2010/07/05/changing-the-team-project-collection-of-the-team-build-controller.aspx" rel="noreferrer">here</a> and <a href="http://social.msdn.microsoft.com/Forums/en/tfsbuild/thread/848bdb21-f9de-4427-ad88-1c0a4928be90" rel="noreferrer">here</a> TFS 2010 does not allow multiple project collections to use a same Build Controller. Why? I'm going to setup some another more build controller as virtual machines. But it seems somehow not practical. Because our company is going to have several project collections. Is it a good work-around? Is there any better work-around except that using a single project collection for all projects?</p>
