Please give a try to this: var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); config.AppSettings.Settings[ Setting1 ].Value = 2.0.2 ; config.Save(ConfigurationSaveMode.Modified true ); ConfigurationManager.RefreshSection( appSettings ); MessageBox.Show(config.AppSettings.Settings[ Setting1 ].Value);
