Vista Tutorial - SOAP headers are not supported by the None MessageVersion.

Hi,
I am very frustrated and cannot seem to figure out a problem.
I created a service (.svc) and when I try to browse it in IIS, I get the following error:

Operation 'ValidateUser' in contract 'ILoginService' uses a MessageContract that has SOAP headers. SOAP headers are not supported by the None MessageVersion.

I have no clue what is going on.

********************
[ServiceContract(
Namespace = "http://schemas.blab.blab",
Name = "ILoginService",
SessionMode = SessionMode.Allowed)]
public interface ILoginService
{
[FaultContract(typeof(DefaultFaultContract))]
[FaultContract(typeof(NullArgumentFaultContract))]
[OperationContract(IsTerminating = false,
IsInitiating = true,
IsOneWay = false,
AsyncPattern = false,
Action = "*",
ReplyAction = "*")]
LoginResponse ValidateUser(LoginRequest request);
}//ILoginService
********************
[MessageContract(WrapperName = "LoginRequest",
WrapperNamespace = "http://schemas.blab.blab")]
public class LoginRequest
{
#region Data Members
private CallingContext _messageContext = new CallingContext();
private LoginDetails _details = new LoginDetails();
#endregion//Data Members

public LoginRequest()
{
}

[MessageHeader()]
public CallingContext MessageContext // defined as DataContract
{
get { return _messageContext; }
set { _messageContext = value; }
}
[MessageBodyMember()]
public LoginDetails LoginDetails // defined as DataContract
{
get { return this._details; }
set { this._details = value; }
}
#endregion//Public Properties

public bool IsValid
{
get { return this._isValid; }
set { this._isValid = value; }
}

in the .svc project web.config I have ...

Can anyone tell me how to fix that error? As I have no clue. Is it an IIS issue, a web.config issue??
Using VS2008 and the projects are set to .NET 3.0 Framework.
Solution builds success.
