Bad request 400 on sending xml request in wcf rest - wcf

Question

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.

Answer 1

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.

Answer 2

Kindly specify The Datacontract Namespace in DataContract Class
[DataContract(Namespace = "http://xxx.xxx.xxx/Service.svc")]
and follow same in Xml file

Answer 3

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>"
