WCF service hosted in a managed Windows service connect using a WCF service application

Question

Thank you in advance for any advice. I have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:

Warning: Type library exporter encountered a type that derives from a generic class and is not marked as [ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be exposed for such types. Consider marking the type with [ClassInterface(ClassInterfaceType.None)] and exposing an explicit interface as the default interface to COM using the ComDefaultInterface attribute.

It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

Any advice?

Ok Fixed this. Was a Permissions Error the iusr account did not have access to the web.config file from the WCF Service Application. So It works now. Now another problem has arised. I need to be able to call the WCF Service Application from asp classic but it does not use a web.config.
