title: Add a WCF service to ASP.NET MVC app and get advantage of existing classes
body: <p>I'll try to explain the situation in the best way possible, I hope someone out there can guide me a bit.</p>
  
  <p>We have a working .NET MVC 4 app where we've added a service reference to consume a WCF external service.</p>
  
  <p>We've created several classes and methods to translate our data model to service's one, so we can call it's different methods from within our app using our data model.</p>
  
  <p>Now we have a new requisite: to add our own service, which can be accessed from outside our environment, and who has to replicate some of the methods of the original service. </p>
  
  <p>The idea is that users will post info to our environment through our service, we'll apply several treatments to the info, and then post it to the original service.</p>
  
  <p>So my question here is: How do I create and attach the new service to my MVC app so I can get advantage of the classes and methods that are already developed and the data model of the original service?</p>
