Soap response to C# class always return null values

I am having hard time parsing soap response from web service and converting it to c# object. What ever i do it always returns null elements. Here is my Response. 

<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' 
 xmlns:tem='http://tempuri.org/'>
 <soapenv:Header/> <soapenv:Body>
 <tem:Response><tem:Result>
  <RETN>108</RETN><DESC> This is an error</DESC></tem:Result></tem:Response>
   </soapenv:Body>
 </soapenv:Envelope>

This is how I am parsing this response. 

var xDoc = XDocument.Parse(response);
var xLoginResult = xDoc.Root.Descendants().FirstOrDefault(d => d.Name.LocalName.Equals("Result"));
var serializer = new XmlSerializer(typeof(Result));
using (var reader = xLoginResult.CreateReader())
{
    var convertedResonse= (Result)serializer.Deserialize(reader);
    // inside this convertedResonse RETN and  DESC is alway null
}

Here is my Result Class

   [XmlRoot(ElementName = "Result", Namespace = "http://tempuri.org/")]
    public class Result
    {
        [XmlElement("RETN")]
        public string RETN { get; set; }
        [XmlElement("DESC")]
        public string DESC { get; set; }
    }

    [XmlRoot(ElementName = "Response", Namespace = "http://tempuri.org/")]
    public class Response
    {
        [XmlElement(ElementName = "Result", Namespace = "http://tempuri.org/")]
        public Result Result { get; set; }
    }

    [XmlRoot(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
    public class Body
    {
        [XmlElement(ElementName = "Response", Namespace = "http://tempuri.org/")]
        public Response Response { get; set; }
    }

    [XmlRoot(ElementName = "Envelope", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
    public class Envelope
    {
        [XmlElement(ElementName = "Header", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
        public string Header { get; set; }
        [XmlElement(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
        public Body Body { get; set; }
        [XmlAttribute(AttributeName = "soapenv", Namespace = "http://www.w3.org/2000/xmlns/")]
        public string Soapenv { get; set; }
        [XmlAttribute(AttributeName = "tem", Namespace = "http://www.w3.org/2000/xmlns/")]
        public string Tem { get; set; }
    }

Values inside convertedResonse is always null. Any thoughts will be much appreciated?

For the Xml posted in the question, you don't need to use XmlSerializer, just XDocument by using Linq to Xml is sufficient, like the following code :

1 - Create NameSpace : 

XNamespace xn = "http://tempuri.org/";

2 - Adapt the query for XDocument to :

Result result = xDoc
    .Descendants(xn + "Result")
    .Select(x => new Result { DESC = x.Element("DESC").Value, RETN = x.Element("RETN").Value })
    .FirstOrDefault();

Console.WriteLine($"DESC:{result.DESC}, RETN:{result.RETN}");

Result

DESC: This is an error, RETN:108

I hope you find this helpful.
