What is the difference between WCF and WPF?

Question

I am a naive developer and I am building up my concepts, I was asked to create a sample application in wcf, and so I am asking a bit subjective question here. I want to know the diffrence and functionality of the above two, in which terms we prefer one over other?

Answer 1

WCF = Windows COMMUNICATION Foundation

WPF = Windows PRESENTATION Foundation.

WCF deals with communication (in simple terms - sending and receiving data as well as formatting and serialization involved), WPF deals with presentation (UI)

Answer 2

The quick answer is: Windows Presentation Foundation (WPF) is basically a way of displaying user interface. (see this)

Windows Communication Foundation (WCF) is a framework for creating service oriented applications. (see this)

As for which one you should use, it depends on your requirement. Usually an application written in WPF, ASP.NET..etc called the WCF service to do some processing at the server-side and the service returns the result to the application that called it.
