We are quickly coming to the fun part. Now that we have our Hello World project constructed, we will learn how to build, compile, and deploy the project. This will allow us to test it on our HoloLens or in the HoloLens emulator. When you begin a new project, the steps given in the subsequent section only have to be done the first time you build and compile. There are quite a few steps; do not let it intimidate you.
