Question

Imagine I have the following, standard WCF, code :

[ServiceContract]
interface ICustomerService {
    [OperationContract]
    Customer GetCustomer();
}

public ICustomerService {
     public Customer GetCustomer() 
     { 
          return MyStore.WhatIsNeeded();
     }
}

This is working well and allows me to distribute the service and the consuming code.

Is it possible (and is it a good idea) to completely bypass the WCF engine if working in a single box ?

In fact, I want the app to be able to run on farm servers, or on small single box servers.

To reduce WCF messaging cost, I’d like to have something like :

ICustomerService service = null;
if(singlebox)
{
    service = new CustomerService(); // Direct instanciation of the service class. No WCF here ...
}
else
{
    service = new CustomerServiceClient(); // Wcf client
}

var cust = service.GetCustomer();

If wrapped properly, can this technique reduce server charge ?

Answer 1

This will surely reduce the overhead of WCF runtime. I’d create a factory class which will check if(singlebox) and new up the right implementation of ICustomerService.
