Scenario 1

The project target frameworks are different than the lock file's target frameworks. Lock file target frameworks: net6.0,net5.0. Project target frameworks net6.0. The packages lock file is inconsistent with the project dependencies so restore can't be run in locked mode. Disable the RestoreLockedMode MSBuild property or pass an explicit --force-evaluate option to run restore to update the lock file.

  • Return the project to it's previous state, removing the additional net5.0 framework.
