Why is the Newtonsoft.Json library not installed via NuGet?

[cristianst85]

Hello.

I've noticed that the Newtonsoft.Json library is not installed via the NuGet package manager. Is there a reason for that?
I am asking because the project already has a packages.config file.

Also, build artifacts like those in the mono directory or the HaveIBeenPwned.plgx file should not be committed to the source control. They can be either distributed via the GitHub Releases page or they can be obtained by manually building the solution.

Best regards,
Cristian
