Dot Net Core - How to Prevent appsettings.production.json from changing upon publish

Question

I'm publishing my .net core website to the server. Here is the code that adds Json files to my content path:

var builder = new ConfigurationBuilder()
                        .SetBasePath(contentRootPath)
                        .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                        .AddJsonFile($"appsettings.{environmentName}.json", true);

and here is how the related part of the solution looks:

In my production computer, I have a appsettings.production.json file. I recently had to manualy add MultipleActiveResultSets=true to my connection string.

But everytime I publish the app, that file is reverted to the previous production configuration.

I don't know where the contents of that file is stored and how it remembers its previous state.
