I just got this error while publishing my first ASP.NET Core application in Self Contained Deployment mode.

Solution

One-liner solution to this problem is - Just repair your Visual Studio.

Though I took some screenshots of repairing steps, I thought attaching those screenshots here might help you.

  1. Step 1: Search for Visual Studio Installer: rzc generate exited with code 1
  2. Step 2: Select repair option rzc generate exited with code 1
  3. Step 3: Click on OK rzc generate exited with code 1
  4. Step 4: At the end, restart the system. rzc generate exited with code 1

After re-starting the system, you will find that issue has been fixed. :)
