WCF Web Services Exits SoapUI

I have the following WCF.Net 4.0 project:

[ServiceContract]
public interface EchoService {
    [OperationContract]
    void Ping();
}

[ServiceBehavior]
public class EchoServiceImpl : EchoService {
    public void Ping() { }
}

I deploy Wether in IIS or run in the debugger, when I connect from SoapUI and try to call the ping command, I end up with a timeout. My intention is to create a service that can be called from Java, but I can't even get the noop ping command to work now.

Is there a way to debug what happens?
