System.IO.FileNotFoundException: Could not load file or assembly 'Newtonsoft.Json, Version=6.0.0.0

I do not get any errors when running on my local dev environment.  But when the code is pushed to a production server, I get the following error.  How can I resolve this issue?  How can I ensure Microsoft.Extensions.Configuration.Json.JsonConfigurationProvider use the latest version of Newtonsoft.Json (8.0.2)???
