WCF service client

Hi

I have the following design:

Data class library (class project) utilizing Microsofts Enteprise Library Data Acess Block.

Service Library (class project) where I have defined my datacontract, service contract, operation contract

Asp.net c# website 

Now In asp.net website code behind I want to call the method I created to fillup my grid.

So I wanted to know how should I create my client and call my method in service library

Thanks
