Staffpad is incredible but it's not brand new or developed by Microsoft. Hanselminutes (Scott Hanselman) did an excellent interview with the engineer who created it a few months back, definitely worth listening to if this piqued your interest. Thoroughly covers how it was conceived and coded in C#/C++, with comments about the relationship to Microsoft: http://www.hanselminutes.com/473/developing-staffpad-a-new-c...
It's actually a project started and run by my brother! I'm tremendously proud of him and what he's achieved with StaffPad, whilst simultaneously running a business as a contract music producer as well no less.
Seeing him on stage with Nadella was a particular highlight.
