Should I ignore the launchSettings.json file from being committed in Git?

launchSettings.json should not be ignored. That repository has since been updated to not ignore it: https://github.com/github/gitignore/pull/2705

Reasons for making this change:

Ignoring launchSettings.json does not make much sense. Now .NET CLI even considers this file when running with dotnet run, as you can read here.

This settings will be useful if shared among project members, so it should be commited to the repo.
