Описание тега wcf-binding
The configuration of encoding, protocol and transport detailing how WCF services and clients communicate with each other. This tag is for both the default system-provided bindings, and custom bindings.
A WCF binding is a combination of encoding, protocol, and transport details used by WCF web services and clients to communicate with eachother. It determines the wire representation of messages exchanged by services and clients.
WCF offers default system-provided bindings for typical combinations, e.g. for typical http or https connections. You can also create custom bindings for your application, detailing non-default options for encoding, transport, and protocol.
