Building HoloLens App with Unity and MRTK Part 1 (Pre-requisitions)

Building your own app for the HoloLens 2 is not a difficult task but requires setting up a development pipeline. Missing a piece of a puzzle can result in a waste of many hours of troubleshooting. We have created this tutorial, based on our experience, to save your time so you can focus on the app itself.

Pre-requisitions:

• A Windows 10 PC: Windows 10 (Manual install link)
• Visual Studio 2019 (16.8 or higher) (Install link)

⚠️ When installing Visual Studio check workloads for Desktop Development with C++,
‍Universal Windows Platform development and Game development with Unity or more if needed.
‍Remember to add ‘C++ (v142) Universal Windows Platform to...’ (it is required and not checked as default) on the right side.

‍

‍

• HoloLens 2 Emulator (Windows Holographic, version 21H2 January 2022 Update) (Install link: 10.0.20348.1010)
• Windows 10 SDK 10.0.18362.0 or later
• Unity Hub with Unity installed:
  - Unity 2020.3.X (to work with recommended OpenXR API which enables building application targeting multiple platforms - new solution, although still with some issues)
  - Unity 2019.4.X (to work with Windows XR plugin - no longer developed)

• Mixed Reality Feature Tool
• HoloLens 2 (Optional)
