There isn't much in the way of HoloLens specific documentation currently, and I'm getting this when I try and launch the unity sample on the hololens: "Vuforia App key is not valid for this product. Please get a valid key, by logging into your account at developer.vuforia.com and choosing the right product type during project creation". Is optical see through not the right option? Is there additional setup options that should be chosen before building out to the hololens?
UPDATE: it appears that both types of developer licenses currently do not work, not sure if this is intended but it's a big problem
