Digging into aogan's answer and combining it with decasteljau's answer and the blog post he referenced, here is an example that fills in some gaps that weren't clear to me.

The xaml file:

And the source file:

namespace MyApp
{
    class MainWindow ....
    {
        ...

        protected override void OnClosing(System.ComponentModel.CancelEventArgs e)
        {
            MyAppSettings.Default.Save();
            base.OnClosing(e);
        }
    }

    public sealed class MyAppSettings : System.Configuration.ApplicationSettingsBase
    {
        private static MyAppSettings defaultInstance = ((MyAppSettings)(global::System.Configuration.ApplicationSettingsBase.Synchronized(new MyAppSettings())));
        public static MyAppSettings Default
        {
            get { return defaultInstance; }
        }

        [System.Configuration.UserScopedSettingAttribute()]
        [System.Configuration.DefaultSettingValueAttribute("540")]
        public int MainWndHeight
        {
            get { return (int)this["MainWndHeight"]; }
            set { this["MainWndHeight"] = value; }
        }

        [System.Configuration.UserScopedSettingAttribute()]
        [System.Configuration.DefaultSettingValueAttribute("790")]
        public int MainWndWidth
        {
            get { return (int)this["MainWndWidth"]; }
            set { this["MainWndWidth"] = value; }
        }

        [System.Configuration.UserScopedSettingAttribute()]
        [System.Configuration.DefaultSettingValueAttribute("300")]
        public int MainWndTop
        {
            get { return (int)this["MainWndTop"]; }
            set { this["MainWndTop"] = value; }
        }

        [System.Configuration.UserScopedSettingAttribute()]
        [System.Configuration.DefaultSettingValueAttribute("300")]
        public int MainWndLeft
        {
            get { return (int)this["MainWndLeft"]; }
            set { this["MainWndLeft"] = value; }
        }
    }
}
