You can consume wcf service in an MVC3 application from either server and
client side[
^]. But server side is a better approach in most cases. You can reference a wcf service in an mvc3 application as in any other .net application (

The answer to the question
where you should put it, depends on the actual service it provides, and where it can be aligned in the model, view and controller concepts.
Folders are just there to guide your towards neat code structuring, nothing more.
