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.
A Silverlight application to poll a service for the latest data feeds. While creating such applications was possible prior to the existence of WCF, WCF makes the development of endpoints easier than ever.
In summary, WCF is designed to offer a manageable approach to creating Web services and Web service clients. Service-oriented architecture SOA is the reliance on Web services to send and receive data.
The services have the general advantage of being loosely-coupled instead of hard-coded from one application to another. A loosely-coupled relationship implies that any client created on any platform can connect to any service as long as the essential contracts are met. Interoperability WCF implements modern industry standards for Web service interoperability.
For more information about the supported standards, see Interoperability and Integration. Multiple Message Patterns Messages are exchanged in one of several patterns. The second endpoint replies. There are other patterns such as a one-way message in which a single endpoint sends a message without any expectation of a reply.
A more complex pattern is the duplex exchange pattern where two endpoints establish a connection and send data back and forth, similar to an instant messaging program. For more information about how to implement different message exchange patterns using WCF see Contracts.
This metadata can be used to automatically generate and configure clients for accessing WCF services. For more information, see Metadata. NET Framework, it also includes code-friendly methods of supplying the contracts you want to enforce.
One of the universal types of contracts is the data contract. In essence, as you code your service using Visual C or Visual Basic, the easiest way to handle data is by creating classes that represent a data entity with properties that belong to the data entity.
WCF includes a comprehensive system for working with data in this easy manner. Once you have created the classes that represent data, your service automatically generates the metadata that allows clients to comply with the data types you have designed.Chapter 1.

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.
