I'm going to clue you in on two of the most popular game engines that people use in the industry, Unity and Unreal Engine.

UnityVS helps developers to more easily debug their Unity scripts and provides code snippets, wizards and other tools. It also provides integration between the Unity console and Visual Studio.

You don’t wear a HoloLens headset to write code or even to test the code you’ve written. Working with Unity, you’ll create a stage, add objects, then start to attach scripts to those objects.
