Multiple interfaces from a single WCF service?

Can a single WCF service offer multiple interfaces, and if so how would you express this in app.config?

I mean one services offering several Interfaces on one endpoint.

From stackoverflow

• First you need to be clear what a service is. Do you mean a single endpoint, or multiple endpoints in the same host?

  Assuming you mean a single endpoint, then yes, but with a little work. An endpoint can only implement a single interface; so what you need to do is combine all the interfaces you want to implement into a single interface

  public interface IMyInterface : IInterface1, IInterface2
  

  and then implement them all inside your implementation class. What you cannot do is have multiple interfaces and multiple implementations magically merge into a single endpoint.

  Peter Wone : Thanks, that's exactly what I was asking.

• With WCF, you can:

  • have one service implementation class that implements multiple service interfaces
  • have one service implementation class exposed through multiple endpoints, e.g. one service endpoint using BasicHttpBinding for maximum interoperability and another endpoint using NetTcpBinding for maximum performance (with WCF clients).

• Here's how you could expose the same interface on two different endpoints in your App.Config if that's waht you are asking.

  <service name="Service1">    
     <endpoint address="http://localhost:8001/service1.asmx" binding="basicHttpBinding" contract="IService" />
  </service>
  <service name="Service2">    
    <endpoint address="http://localhost:8002/service2.asmx" binding="basicHttpBinding"  contract="IService" />
  </service>
