How to deserialize XML string to object

From a web service I'm getting an XML string, which I need to map on an object. I am trying to map below XML to an object but the entries are null.

<?xml version=\"1.0\" encoding=\"utf-8\"?>

Here's how I'm calling the service and reading the response:

var credentials = new NetworkCredential(usr, pwd);
var request = (HttpWebRequest)WebRequest.Create("......");
request.Credentials = credentials;
var res = request.GetResponse();

var stream = res.GetResponseStream();
var reader = new StreamReader(stream, System.Text.Encoding.GetEncoding("utf-8"), true);
string strResponse = reader.ReadToEnd();

var strReader = new StringReader(strResponse);
var serializer = new XmlSerializer(typeof(EPMProjects));
var xmlReader = new XmlTextReader(strReader);
var obj = serializer.Deserialize(xmlReader);

And the model class to get mapped on:

[XmlRoot("feed", Namespace = "http://www.w3.org/2005/Atom")]
public class EPMProjects
{
    [XmlElement("entry")]
    public List<EPMProject> Projects { get; set; }

    public EPMProjects()
    {
        Projects = new List<EPMProject>();
    }
}

public class EPMProject
{
    [XmlElement("ProjectName")]
    public string ProjectName { get; set; }
}
