WCF + WebGet => Http Bad request 400

See more:

ASP.NET

I am stuck since severals hours on that problem and i need someone to point me out my mistake.

The VS2010 project is configured to run on the 2722 port with the Visual Studio Development Server.

When i try to browse this url :
http://localhost:2722/Web/EmployeeService.svc/GetEmployee/1

I get the following error :
Http 400 bad request.

And in the WCF log file :
The body of the message cannot be read because it is empty.

Thanks for your time!


Below, the files :

----------------------------
Interface :
Web/IEmployee.cs
----------------------------

namespace WcfServices.Web
{
    [ServiceContract]
    interface IEmployee
    {
        [WebGet(UriTemplate = "GetEmployee/{id=1}")]
        [OperationContract]
        Employee GetEmployee(String id);
    }
}

----------------------------
The implementation :
Web/EmployeeService.cs
----------------------------

namespace WcfServices.Web
{
[AspNetCompatibilityRequirements(RequirementsMode=AspNetCompatibilityRequirementsMode.Allowed)]
    public class EmployeeService : IEmployee
    {
        private IList<Employee>_list = new List<Employee>();

        EmployeeService()
        {
            _list.Add(new Employee() { Id = 1, FirstName = "Joe", LastName = "Dalton"});
            _list.Add(new Employee() { Id = 2, FirstName = "Luke", LastName = "Lucky" });
            _list.Add(new Employee() { Id = 3, FirstName = "Ma", LastName = "Dalton" });
            _list.Add(new Employee() { Id = 4, FirstName = "Rantanplan", LastName = "Unknow" });
        }

        Employee IEmployee.GetEmployee(String id)
        {
            int __id;
            if (int.TryParse(id, out __id))
            {
                return _list[__id];    
            }
            return null;
        }
    }
}

--------------------------------------
The data structure :
Data/Employee.cs
--------------------------------------

namespace WcfServices.Data
{
    [DataContract]
    public class Employee
    {
        [DataMember]
        public int Id { get; set; }
        [DataMember]
        public string LastName { get; set; }
        [DataMember]
        public string FirstName { get; set; }
    }
