How do I deserialize a user.config file?

Question

So I have this auto-generated user.config file. What I'm trying to do is deserialize the XML and put that data I need into properties. The class is just properties the XML data should go into. Right now the properties are all showing null. Don't know what else is needed to get the data. Should I be using XmlSerializer.Deserialize? Or is something else? What's the best way to tackle this problem?

The class is just properties the XML data should go into.

        [Serializable, XmlRoot(ElementName = "configuration")]
        public class UserConfig
        {
           public UserConfig() { }

                   private bool ReadUserConfigXML(string xmlFilePath = "")
    {
        if (xmlFilePath != string.Empty) { _xmlFilePath = xmlFilePath; }
        var xmlSerializer = new XmlSerializer(typeof(UserConfig));
        bool userConfigExists = File.Exists(_xmlFilePath);
        if (userConfigExists)
        {
            using (FileStream xmlFileStream = new FileStream(_xmlFilePath, FileMode.Open))
            {
                _userConfig = (UserConfig)xmlSerializer.Deserialize(xmlFileStream);
            }
        }

        return userConfigExists;
    }            

           [XmlElement("userSettings")]
           public UserSettingsProperties UserSettingsPropertiesData {get; set;}
        
           public class UserSettingsProperties
           {
                    public UserSettingsProperties()
                    {
        
                    }
        
                    [XmlElement("Project1.Setting.Properties.Settings")]
                    public SettingsProperties SettingsPropertiesData { get; set; }
                    [XmlElement("Project1.Echos.Tires.Properties.Settings")]
                    public TiresProperties TiresPropertiesData { get; set; }
                    [XmlElement("Project1.Echos.Axles.Properties.Settings")]
                    public AxlesProperties AxlesPropertiesData { get; set; }
        
                    public class SettingsProperties
                    {
                       public SettingsProperties()
                       {
        
                       }
        
                       public string RPMs {get; set;}
                       public string Body {get; set;}
                       public string WindResistance {get; set;}
                    }
           }
       }

Here is one example using XDocument to read one project settings.

var xml = XDocument.Load("XMlFile1.xml");
var results = xml.Descendants("userSettings")
                    .Select(x => x.Element("Project1.Setting.Properties.Settings"))
                    .Descendants("setting")
                    .Select(x=>new
                    {
                        name = x.Attribute("name").Value,
                        serializeAs = x.Attribute("serializeAs").Value,
                        value = x.Element("value").Value
                    });
