In Visual Studio 2013 and Team Explorer 2013 there is a bug that will cause the “What do you want to build?” combo box to be disabled and the entire Parameters tab to be blank. We have now released a patch to fix this bug: KB 2898341. This bug occurs when using VS or TE 2013 with a TFS 2013 server. We introduced the bug at the very end of the release when we made a performance optimization for builds on the server used by the Developer Division.
