HoloLens Dev 101: How to Use Holographic Remoting to Improve Development Productivity

Way back, life on the range was tough and unforgiving for a HoloLens developer. Air-tap training was cutting edge and actions to move holograms not called "TapToPlace" were exotic and greeted with skepticism. The year was 2016, and developers had to deploy to their devices to test things as simple as gauging a cube's size in real space.
