Deploying the app to the device

Using the emulator can be a great tool in your toolbox, especially when you are working in a team; having a device for each developer is usually not an option. The devices are pretty expensive, and you don't need one to develop your app. Of course, when you are working on a project, it is invaluable to deploy to the device every now and then and see how your code behaves in the real world. After all, you can only experience the true power of the HoloLens by putting it on.

So, we need to deploy the code to the device. First of all, you need to make sure that you have the Developer Mode switched on. You can do this by going to the Settings app and selecting the For Developers option in the Update part. There, you can switch the Developer mode on.

Once you have done this, you can start the deployment from Visual Studio to the device. To do this, you have two options:

• Use Wi-Fi deployment
• Use USB deployment

Since you already have set up the device to use the network, you can use the option. This one tends to be slightly slower than using the USB deployment, but it has the advantage that you can do this without having a wire attached to the device. Trust me--this has some advantages. I have done a deployment through USB only to discover I could not immediately stand up and walk around my holograms--I forgot the cable was still attached to the device.
