Developing applications and experiences for HoloLens is not hard to get started with, but after you have started a number of projects and worked through the same setup and plumbing a few times, you wish there was an easier way to do it. Well, there is! Created by the team that produced Fragments and Young Conker, the HoloToolkit is a collection of scripts and components intended to accelerate the development of holographic applications targeting Windows Holographic.
The toolkit is all free and comes in two varieties: one for Visual Studio and one for Unity 3D. Developing for HoloLens means spending a LOT of time in the Unity editor, and the HoloToolkit is a simple .unitypackage file you can download and import into your Unity project.
