How to edit application configuration settings? App.config best way to go?

Question

For my project I have settings that I added through the Settings in the project properties.

I quickly discovered that editing the app.config file directly seems to no really update the settings value. Seems I have to view the project properties when I make a change and then recompile.

• I'm wondering ... what is the best and easiest way to handle customizable settings for a project -- thought this would be a no-brainer with how .Net handles it ... shame on me.

• Is it possible to use one of the settings, AppSettings, ApplicationSettings, or UserSettings to handle this?

Is it better to just write my settings to custom config file and handle things myself?

Right now ... I am looking for the quickest solution!

My environment is C#, .Net 3.5 and Visual Studio 2008.

Update

I am trying to do the following:

    protected override void Save()
    {
        Properties.Settings.Default.EmailDisplayName = this.ddEmailDisplayName.Text;
        Properties.Settings.Default.Save();
    }

Gives me a read-only error when I compile.

This is silly ... and I think I am going to have to apologize for wasting everyone's time! But it looks like I just need to set the scope to User instead of Application and I can the write the new value.
