I'll try to explain the situation in the best way possible, I hope someone out there can guide me a bit.
We have a working .NET MVC 4 app where we've added a service reference to consume a WCF external service.
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.
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.
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.
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?
