Windows Communication Foundation



WCF (Windows Communication Foundations) is framework designed in accordance with Service Oriented Architecture principles to support distributed computing, multiple services and services can be consumed by multiple clients.  (Services coupled Language) which any WCF client can use to consume the service, irrespective of which Platform the service is hosted on.

WCF implements many advanced Web Services (WS) standards such as where services are consumed by consumers. Clients can consume loosely to each other.   Services typically have a WSDL interface (Web Services Description WS-Addressing, WS-Reliable Messaging and WS-Security.




How it Works?
Client and Service communicate with each other by sending messages as service on
locally or remotely distributed networks.

Basic Client Server Communication
 
Client HTTP/TCP /MSMQ HTTP/TCP/MSMQ Server, SOAP Message

Message
A self-contained unit of data that can consist of several parts, including a body and
headers.
 
Service
A construct that exposes one or more endpoints, with each endpoint exposing one or
more service operations.

Endpoint
A construct at which messages are sent or received (or both). It comprises a location (an
address mechanism (a set of messages that can be sent or received (or both) at that location contract. WCF Service is exposed to the world as a collection of endpoints that defines where messages can be sent, a specification of the communication binding that described how messages should be sent, and a definition for a service that describes what message can be sent.
