Answer 1

    public static void SetAppSettingValue(string key, string value, string appSettingsJsonFilePath = null)
    {
        if (appSettingsJsonFilePath == null)
        {
            appSettingsJsonFilePath = System.IO.Path.Combine(System.AppContext.BaseDirectory, "appsettings.json");
        }

        var json =   System.IO.File.ReadAllText(appSettingsJsonFilePath);
        dynamic jsonObj = Newtonsoft.Json.JsonConvert.DeserializeObject(json);

        jsonObj[key] = value;

        string output = Newtonsoft.Json.JsonConvert.SerializeObject(jsonObj, Newtonsoft.Json.Formatting.Indented);

        System.IO.File.WriteAllText(appSettingsJsonFilePath, output);
    }
