Sharing this in case anyone else has issue with Debugger during the Inventory course Debugger section.

Unity 2020. 2.4f1
Visual Studio Community 2019 V.16.8.2
Windows 10

ISSUE DESCRIPTION:
Debugger would not auto stop like shown in the course after adding the Debug break points on the left side (or with f9 when cursor is on line).

POSSIBLE FIX [1]:
Description: Unity is unable to update certain files to allow crosstalk between programs. Run as administrator to fix.
Steps:

  • Close Unity and VS
  • Add shortcut to Unity to desktop
  • Right click Unity shortcut > Properties > Advanced > Run as Administrater > Close Popup > Apply
  • Reopen Unity and VS script for debuggin
  • In VS at top click “Attach to Unity”
    NOTE: May need to click popup option appearing in Unity
  • In Unity at top click “Play” button

POSSIBLE FIX [2]
Description: VS has a possible corrupted or bugged solution. Rebuild it to fix.

  • In VS click “Build” > “Rebuild Solution”.

I’ve previously had problems with Unity / VS debugger not connecting - though not for a couple of years now.

Typically my fix was (in order of pain descending):

  1. Do a VS update: Help → Check for Updates (warning, big download ahead)
  2. Run the Visual Studio Installer and remove / add the ‘Game Development with Unity’ workload.
  3. Worst case I’d download a new version of Unity via the Unity Hub.

Obviously try closing and reopening Visual Studio / rebooting your PC before trying the above.
