A new series of tutorials has been posted for HoloLens 2. They will be maintained to continue working on the supported devices. These tutorials will not be updated with the latest toolsets or interactions being used for HoloLens 2 and may not be compatible with newer versions of Unity. As such, we feel it is important to leave these tutorials in place for developers who are still looking for guidance in developing for those devices. The Mixed Reality Academy tutorials were designed with HoloLens (1st gen), Unity 2017, and Mixed Reality Immersive Headsets in mind.
