in .net core you can use ConfigurationBuilder to read appsettings.json file.

You can implement like following.

appsettings.json sample

{
  "option1": "value1_from_json",
  "option2": 2,

  "ConnectionStrings": {
    "YourConnectionString": "............."
  }
}

C# code sample

static class YourClass
{
    public static IConfigurationRoot Configuration;

    public static string GetConnectionString()
    {
         var builder = new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("appsettings.json");

         Configuration = builder.Build();
         var connectionString = Configuration["ConnectionStrings:YourConnectionString"];

    }

}
