Bad request 400 on sending xml request in wcf rest

I am writing a sample application using wcf rest for authentication. Here is the snapshot of the code:

service Interface:

[ServiceContract]
public interface IAuthenticate
{
    [OperationContract]
    [WebInvoke(BodyStyle=WebMessageBodyStyle.Bare, 
Method = "POST", UriTemplate = "/VUser",RequestFormat= WebMessageFormat.Xml ), ]
    string CreateUser(VUser user);
}

Datacontract class:

[DataContract]
public class VUser
{
    public VUser()
    {
    }

    [DataMember]
    public string NickName { get; set; }

    [DataMember]
    public string lName { get; set; }

    [DataMember]
    public string fName { get; set; }

    [DataMember]
    public string Email { get; set; }

    [DataMember]
    public string PhoneNumber { get; set; }

    [DataMember]
    public string Password { get; set; }

    [DataMember]
    public string Gender { get; set; }

    [DataMember]
    public int CountryCode { get; set; }
}

Service class:

public class Authenticate : IAuthenticate
{

    #region IAuthenticate members
    public string CreateUser(Vuser user)
    {
        //processing xml for response

    }
    #endregion IAuthenticate
}

client code:

       Uri baseAddress = new Uri("http://localhost:8000");

        using (WebServiceHost host = new WebServiceHost(typeof(Authenticate), baseAddress))
        {
            host.Open();
            Console.WriteLine("Press any key to terminate");
            Console.ReadLine();
            host.Close();

        }

Now I am using fiddler to send the request after host.open() and send the the request has shown:

post http://localhost:8000/Vuser/

User-Agent: Fiddler Host: localhost:8000 content-length: 233 content-type: text/xml

and in request body :

sandy r sunil sunil.r 919900101948 winter male 01

but it is returning me HTTP/1.1 400 Bad Request. My question is am I passing the vuser class correctly to the create user method or is there any other way to send the vuser.

Please help me.

The Namespace in both client and server should match. Try to add namespace name as

[DataContract(Namespace = "http://sample.com")]
public class VUser

in the server contract. And then make sure the xml string has the xmlns value with the same namespace

"<VUser xmlns=\"http://sample.com" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">...</VUser>"

Kindly specify The Datacontract Namespace in DataContract Class

[DataContract(Namespace = "http://xxx.xxx.xxx/Service.svc")]

and follow same in Xml file

It could be a problem with serialization.

Serialization uses the default consrtuctor, without parameters.

In C# the compiler will automatically create a default constructor, except if you create a constructor with a parameter.

The Authenticate class is missing a default constructor, you will therefore have probelms sending it over WCF.
