I desprately trying to solve the following prob.
I have a c# class method that returns an Interface:
    [InterfaceType(ComInterfaceType.InterfaceIsDual)]
    public interface IDocument

Check out the documentation for TcpClientChannel.ChannelName
ms-help://MS.VSCC.2003/MS.MSDNQTR.2005JAN.1033/cpref/html/frlrfsystemruntimeremotingchannelstcptcpclientchannelclasschannelnametopic.htm
This is the declaration
public virtual string ChannelName {get;}
