I’ve updated this tutorial to use the MixedReality Toolkit packages, which is a great improvement. (Nice job MRToolkit team, this was a huge step forward in usability!) I’ve also updated the tutorial to use Unity 2017.1 and the latest Visual Studio 2017. There is an incompatibility between 2017.1 and VS 2017 so make sure to update to the latest patch level that I have linked in the index. The good news is that no code changes were required. This updated version has been checked into Github. Unfortunately the HoloLens Emulator is out of date and no longer works with this tool chain.
