Course Fee:    Rs. 25,000/-

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.
