How to debug a unity c# project on hololens

Question

I have developed an application for hololens with Unity that uses the Hololens' depth camera. I built it with il2cpp scripting backend and it runs well on the Hololens when I launch it from Visual Studio 2017 (community). But I want to be able to debug the app (and have the output in visual studio console) while it is running on the Hololens (because I need the camera frame to be received to see how it works).

Moreover, I want to be able to set breakpoints in my .cs scripts files in my #UWP script parts.

I have been searching for a long time on Microsoft documentation and didn't find the specific answers I was looking for.

Answer 1

I found the answer to my problem!

In order to debug c# code directly running on the Hololens, I did as follow:

• In Unity :
  • Build Setting -> Player settings -> Other settings -> Scripting backend = .NET
  • Build Settings :
    • Build configuration Debug
    • check Copy reference
    • check Unity c# project
    • check development build
  • Then you can build
• In Visual Studio 2017
  • Debug - x86 - Device (or remote machine)
  • If needed : In Solution Explorer -> For each solution -> alt+Enter -> Under Build tab check Allow unsafe code

Then you can set your break points where ever you want !

Hope this helps
