Create proxy to an object created by a wcf service class

Question

Hi
We are trying to develop a WCF Service which is configured as per-session.
The service object creates another object which has some data + functions, and has its own Interface which is available on both client and server.
Is it possible to somehow create a proxy of this object on the client so that the client can call the object functions directly ?
Thanks
Abhishek
PS:
The object interface is also configured as a servicecontract and the object class is also configured as a service. However if we call this service independently, it creates a new instance of the object.

Hi Amy
Many thanks for replying.
OK let me try to explain by way of example code appended after my signature.
Let us say we have a service which implements Iservice1. The service contract has an operation returning an object of type Userinfo. In addition to data, the userinfo class has a method GetHistory which returns a datatable.
Datacontract and Datamember attributes will cause the UserInfo object to be recreated on the client. But what I really want is a proxy to this userinfo object, so that the GetHistory function can be called directly rather than going through Iservice1.
In general, I want the service class to be able to create a server object and then let the client have its proxy.
Kindly advise.
Thanks
Abhishek
