http://blogs.iis.net/bills/archive/2008/06/01/how-do-i-script-automate-iis7-configuration.aspx

using(ServerManager mgr = ServerManager.OpenRemote("Some-Server")) {

  Configuration config = mgr.GetWebConfiguration("site-name", "/test-application");

  ConfigurationSection appSettingsSection = config.GetSection("appSettings");

  ConfigurationElementCollection appSettingsCollection = appSettingsSection.GetCollection();

  ConfigurationElement addElement = appSettingsCollection.CreateElement("add");
  addElement["key"] = @"NewSetting1";
  addElement["value"] = @"SomeValue";
  appSettingsCollection.Add(addElement);

  serverManager.CommitChanges();
}
