this Operation is not supported in WCF Test Client Error

Actually i implemented WCF service in IIS Host

Using WCF Test Client tool I get this error: "this Operation is not supported in WCF Test Client".

http://desbiz:49615/GestionProvision.svc

Using wsdl in IExplorer all is ok.

http://desbiz:49615/GestionProvision.svc?wsdl

The contract is:

namespace Security.Provision.ServiceContracts.Interfaces

{

[ServiceContract(Namespace = "http://Security.Provision")]

public interface IProvision

{

[OperationContract]

RespuestaProvision CrearUsuario(PeticionUsuarioProvision peticion);

[OperationContract]

RespuestaProvision ModificarUsuario(PeticionUsuarioProvision peticion);

[OperationContract]

RespuestaProvision BajaUsuario(PeticionUsuarioProvision peticion);

[OperationContract]

RespuestaProvision HabilitarDeshabilitarUsuario(PeticionUsuarioProvision peticion);

[OperationContract]

RespuestaProvision SavePuestoTipo(PeticionPuestoTipoProvision peticion);

[OperationContract]

Respuesta开发者_如何学编程ObtenerEmpleado GetEmpleado(PeticionUsuarioProvision peticion);

}

}

May i know the reason.

Thanks in advance.

You must be using some DataSet or DataTable witn [DataMember] attribute in some custom type, is ok for WCF but the test application cant handle it.

You should also check the you are not using any 'Tuple' as this was not working for me.

[DataMember(Name = "IPAddresses")]
public List<Tuple<IPAddress, IPAddress>> IPAddresses { get; set; }
