Configuring System-Provided Bindings
Bindings specify the communication mechanism to use when talking to an endpoint and indicate how to connect to an endpoint. Bindings consist of elements that define how the Windows Communication Foundation (WCF) channels are layered up to provide the required communication features. A binding contains three types of elements:
-
Protocol channel binding elements, which determine the security,
reliability, context flow settings, or user-defined protocols to use
with messages that are sent to the endpoint.
-
Transport channel binding elements, which determine the underlying
transport protocol to use when sending messages to the endpoint, for
example, TCP or HTTP.
-
Message encoding binding elements, which determine the wire encoding to
use for messages that are sent to the endpoint, for example, text/XML,
binary, or Message Transmission Optimization Mechanism (MTOM).
This topic presents all of the system-provided Windows Communication Foundation (WCF) bindings. If none of these meets the exact requirements for your application, you can create a binding using the CustomBinding class. For more information about creating custom bindings, see Custom Bindings .
