What are you most proud of on HoloLens 2? | One Dev Question

It's time for another #OneDevQuestion with @gbury82. This time we are talking about our path forward for developers in the near term. If you want to join the conversation on Slack, do so at aka.ms/holodevelopers.

Is there anyway decrease the build time with Unity 2019.4.12f1/Visual Studio 2019 for the Hololens2? I am experiencing extraordinarily long build/deploy times for a trivial project (one cube) in the range of 3-4 minutes. This is far, far longer than with Hololens and Unity 5.x.
