Discovery service name and namespace

Setting the name and the namespace of a WCF service for discovery announcement can be done using the ServiceContract attribute properties
For an example:
[ServiceContract(Namespace=@"Com.myCompany.Services",Name="IMyServiceAlias"

)]
public interface IMyService

The change can be seen using Wireshark
