Advantage of Windows Communication Foundation(WCF)

Question

1- WCF has support for multiple protocols (TCP/IP, HTTP, PIPE, MSMQ etc.).
2- WCF can be hosted outside if IIS ie: can be hosted in managed windows applications, a windows service, and WAS (Windows Process Activation Service).
3- WCF provides customisation such as event hooks into service start / end / init / custom global error Handling etc. etc.
4- WCF services supports standard web services ws-*. wsHttpBinding
5- WCF uses http endpoint for web services.
6- It uses schemas and contracts instead of classes & types to define and implement communication.
7- WCF services expose endpoints that clients and services use to exchange messages. Each endpoint consists of an address, a binding, and a contract.
8- The main three elements of WCF architecture are : Address, Binding & Contract.
9- Address :It specifies where service is located and format is network protocol specific e.g. http or tcp.
10- Binding :It specifies transport protocol, security requirements & message encoding to be used by client & service for communication.
11- Contract :It defines what the service can do. WCF service publish multiple types of contracts like service contract, message contract, data contract etc.
