This is my code:
Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
KeyValueConfigurationCollection settings = configuration.AppSettings.Settings;
settings["IP"].Value = "10.0.0.2";
configuration.Save(ConfigurationSaveMode.Modified);
when I break on settings["IP"].Value
line, i get the correct value.
The method completes without any errors but app.config file remains unchanged.

This code should work:
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings["IP"].Value = "10.0.0.2";
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");

As per my knowledge you can't persist the updated value in App.config
.
If you want to persist the config value,do the normal XML operation.
