well thats not exactly what i ment i ment that you should build a master service this service will provide as a router going to all other services and aggregate the information. this is called in WCF - ESB you can have a look at a very nice one called iserviceoriented the UI will talk to the WCF and WCF will talk to all other service regarding the issue of accessing via Interfaces i can recommend you to take a look at unity this is an injection Library for the client to access the Services BL with interfaces while decoppeling the changes to a single point of changes if needed

Hi Thank you for your response. I believe you are suggesting to Group the classes(Services) and access them through Interface. For all these Services there will be a master service which will be used as entry point for all the Users. Can I have an Example to have Clear understanding. Thanks in Advance. SUNJIB MOHANTY

well my friend this is a very nice project and a very nice question the way i see it you should split the architecture into 4 pieces: 1. DAL - which will conect to all services 2. BL - which will be the WCF 3. COMMON - which will hold all the common objects 4. UI - only User Interface as for how to split it wheter for 1000 classes or 1000 service the question is not quite what it seems the idea is to have a class per module and not per instance of type meaning that if you have like HR than you dont create a service just for HR you create a service called UserManager which will provide the User Managment for all User Types. and another service for the DATA Access of the HR business the idea i am saying is you should build an orchestra of Services 1 master and he will call the other services by the requested operations aggregate the data and return it to the BL  the data manipulation will be in the BL and sent into UI for display
