Answer 1

I am totally agree with solution suggested by @Hoot but i have modified class little. i have modified class because i need to pass dynamic Key to fetch value for same..

Configuration Class :

public class ConfigHelper
    {

        private static ConfigHelper _appSettings;

        public string appSettingValue { get; set; }

        public static string AppSetting(string Key)
        {
          _appSettings = GetCurrentSettings(Key);
          return _appSettings.appSettingValue;
        }

        public ConfigHelper(IConfiguration config, string Key)
        {
            this.appSettingValue = config.GetValue(Key);
        }

        public static ConfigHelper GetCurrentSettings(string Key)
        {
            var builder = new ConfigurationBuilder()
                            .SetBasePath(Directory.GetCurrentDirectory())
                            .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
                            .AddEnvironmentVariables();

            IConfigurationRoot configuration = builder.Build();

            var settings = new ConfigHelper(configuration.GetSection("AppSettings"), Key);

            return settings;
        }
    }

Appsettings.Json Configuration:

 "AppSettings": {
    "WebApplicationUrl": "http://localhost:0000/",
    "ServiceUrl": "http://localhost:0000/",
    "CommonServiceUrl": "http://localhost:0000/"
  }

Calling Example:

string ServiceUrl = ConfigHelper.AppSetting("ServiceUrl");

So from now we are able to pass dynamic key.
