What Is Windows Communication Foundation (WCF)

Windows Communication Foundation (WCF) is a framework for building service-oriented applications. 
Using WCF, you can send data as asynchronous messages from one service endpoint to another. 
	
  	- A service endpoint can be part of a continuously available service hosted by IIS, 
		or it can be a service hosted in an application. 
        An endpoint can be a client of a service that requests data from a service endpoint. 
        The messages can be as simple as a single character or word sent as XML, 
		or as complex as a stream of binary data. A few sample scenarios include:

	- A secure service to process business transactions.

	- A service that supplies current data to others, such as a traffic report or other monitoring service.

	- A chat service that allows two people to communicate or exchange data in real time.

	- A dashboard application that polls one or more services for data and presents it in a logical presentation.

		Exposing a workflow implemented using Windows Workflow Foundation as a WCF service.

	- A Silverlight application to poll a service for the latest data feeds.

	WCF includes the following set of features.
