Failed to save custom configuration section in app.config

Question

I am trying to save a custom section in my app.config. This is the code that I still have:

Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); //Read the TunnelSection from the configuration file TunnelSection tunnels = ConfigurationManager.GetSection("TunnelSection") as TunnelSection; HostConfigElement newhost = new HostConfigElement(); newhost.Password = "hola"; newhost.SSHPort = 22; newhost.SSHServerHostname = "holahola"; TunnelConfigElement newtunnel = new TunnelConfigElement(); newtunnel.LocalPort = 12; newtunnel.RemotePort = 12; newtunnel.Name = "12"; newtunnel.DestinationServer = "12"; TunnelCollection newtunnelcollection = new TunnelCollection(); newtunnelcollection.Add(newtunnel); newhost.Tunnels = newtunnelcollection; tunnels.Tunnels.Add(newhost); ConfigurationManager.RefreshSection("TunnelSection"); configuration.Save(ConfigurationSaveMode.Full); 

The problem is that the configuration file does not change. If I go through TunnelSection, I see that a new host has been added.

To eliminate permission issues, I tried adding a parameter to appsettings as follows:

 configuration.AppSettings.Settings.Add("hola", "hola"); 

and it works great.

I also tried saveas, but to no avail.

Any ideas? TIA

System settings cannot be changed, but user settings can be made. User settings are not saved in the application directory, but stored in / appData //. Please check in this place.
