| + | ==== Binding ==== | ||
| + | |||
| + | Bindings are nothing but the transport protocols that are used for the communication with the client application. WCF provides a wide range of transport protocols that can be used as in the requirements. | ||
| + | |||
| + | A binding has the following characteristics: | ||
| + | |||
| + | * Transport: Defines the base protocol to be used, like HTTP, Named Pipes, TCP and MSMQ are some of the protocols. | ||
| + | * Encoding (Optional): Three types of encodings are available, they are: | ||
| + | |||
| + | - Text Encoding | ||
| + | - Binary Encoding | ||
| + | - Message Transmission Optimization Mechanism (MTOM) | ||
| + | |||
| + | * Protocol (Optional): Defines the information to be used in the binding such as Security, transaction or reliable messaging capability. | ||

You can define one or more endpoints for a service by using a combination of relative and absolute endpoint addresses, or if you do not define any service endpoints, the runtime provides some by default for you. | Endpoints provide clients with access to the functionality a Windows Communication Foundation (WCF) service offers.
