ABC of WCF

ABC of WCF is “Address, Binding and Contract”. Address part specify where the service is available. Binding part specify which protocol and encoding method, service is using. And Contract specify which message format, service is expected from the client.

Address:

Binding:

WCF supports following in-build binding:

1. basicHttpBinding
2. wsHttpBinding
3. wsDualHttpBinding
4. wsFederationHttpBinding
5. netTcpBinding
6. netNamedPipeBinding
7. netMSMQBinding
8. netPeerTcpBinding
9. webHttpBinding

Binding gives information about the protocol and encoding method to send the message.
