I have a service hosted that have two interface A and B. I'm trying to implement proxy class for my client by using ClientBase. However, I don't know how to declare it.

This is what I thought it should be:

```
public class ServiceProxy : ClientBase<IA>, ClientBase<IB>, IA, IB
{
.......
}

```

Is that the right way to declare it ? If not, what would be the correct way ? Thank you.
