For years Brian Keller has been delivering a fully functional TFS VM together with a great set of hands-on-labs, everything an ALM expert needs to keep his knowledge up-to-date.
Last year Brian moved away from his role as evangelist for Microsoft ALM, luckily his colleague Sachin Hridayraj continued the story. Yesterday he released a brand new Visual Studio 2015 version, complete with a revised set of hands-on-labs and demo scripts, at http://aka.ms/ALMVMs.
