Introduction To WCF (Windows Communication Foundation)

• It Stands for Windows Communication Foundation
• it was introduced in ASP.NET 3.0.
• We can built the Distributed(Connected System) and Inter-operable Applications.
• Distributed Application (Connected System):
•  Distributed Application is an Application it runs two or   More Computer Nodes.
• Inter-operable Application :
• Inter-operable Application can communicate with other application that was built on any other platform that may developed in java or PHP but it was not work for Remoting Services.

Before WCF ,we have 3 Services

1.  Enterprise Services
2.  Dot Net Remoting
3.  Web Services

Example
 we have two clients
Client 1:
  Requirements are HTTP Protocol and XML message format
Client 2 :
  Requirement are TCP protocol and Binary Format

so above two clients are different if we have one client his requirements are TCP protocol and Binary format but developer should know every thing so Microsoft decided to unify and bring these communication under one root. that is the Windows Communication Foundation
