//Method in Service B
[OperationContract]
DataTable TestMethodInB
(
Int32 EmployeeId
);
When A consume this method of B it will return DataTable(You can change it to any custom object or any data type as per your requirement).
So then in A you can call this method like this -
BClient bclient= new BClient("Endpoint"); //change endpoint as per your proxy endpoint name
DataTable dt = bClient.TestMethodInB(employeeId);
// Once you get datatable or custome object you can work on that in Service A.
Let me know if you are looking for anything else.
