auto generate callback class at duplex /WCF

I'm trying to set duplex service. I have created 2 interfaces: the first - the interface which the server implement:

[ServiceContract(CallbackContract = typeof(IBackUpServiceCallback))]
public interface IBackUpService

with some methods which are implement by the serve and the second one:

public interface IBackUpServiceClient

which holds methods that the server is supposed to use when callback the client. The implement class name 

 BackUpServiceCallBack : IBackUpServiceClient

is at the client side.

The problem is - after I am adding the service - the compiler auto generate: 

interface IBackUpServiceCallback

and demand me to implement it. and i have 2 callback interfaces. the first which i have implemented (BackUpServiceClalBack) at the client side, and the second one name :IBackUpServiceCallback - and I cant control it (client Url is "tempuri..")

and even if BackUpServiceClalBack implements IBackUpServiceCallback - it doesn't get to the implement method during runtime.

I am working with wsDualHttpBinding Binding.

Any ideas?

i figure out that i dont have to do "add service reference' at all. and becuse the client know's the Interface at design time i can use it.

now i wont have a genareted code calss. as well insted of Proxy i will use :

    private DuplexChannelFactory<IBackUpService> factory;
    private IBackUpService _proxy;
    InstanceContext t = new InstanceContext(implementClass);
    factory = new DuplexChannelFactory<IBackUpService>(t, "nameOfBinding");

    _proxy = factory.CreateChannel();

and the binding itself will be at runtime.
