Web binding This binding is provided by the WebHttpBinding class. This is very much used with social networks for implementing a syndication feed. It is like a WsHttpBinding except it supports bi-directional communication which means both clients and services can send and receive messages. It uses TCP protocol for communication between two machines within intranet means same network. It encodes the message in binary format.
This is a faster and more reliable binding compared to the HTTP protocol bindings. It uses named pipe for communication between two services on the same machine. This is the most secure and fastest binding among all the bindings. It uses MSMQ for transport and offers support to a disconnected message queued.
It provides solutions for disconnected scenarios in which the service processes the message at a different time than the client sending the messages.
It is a specialized form of WS binding and provides support to federated security. It uses the TCP protocol, but uses peer networking as transport. In this networking each machine node acts as a client and a server to the other nodes. This is used in the file sharing systems like a Torrent. When to use which bindings in WCF WCF comes with the number of built-in bindings and this article describes the pros and cons of each of these bindings.
It will help you to choose appropriate bindings depending on your requirements and create endpoints for communicating with clients.
WCF bindings decide how the Windows Communication Foundation service endpoint should communicate with clients. Each WCF service endpoint requires binding to be specified, if not set explicitly it uses default basicHttpBinding. It gives communication details and defines below things. With WsHttpBinding messages are encrypted by default and achieve message level security.
This binding supports reliability, transactions, and security over the internet. In some scenarios when client makes a call to WCF service after processing running request service has to call client application for example, updating shipment details to client application. You can implement a Duplex message exchange pattern with wsDualHttpBinding.
This is secure binding is used to send binary encoded SOAP messages within intranet computers. It supports reliability, transaction, and security. When your WCF service and its clients reside on the same computer netNamedPipeBinding is the best choice and gives the best performance over other bindings. The information in a binding can be very basic, or very complex. The most basic binding specifies only the transport protocol such as HTTP that must be used to connect to the endpoint.
More generally, the information a binding contains about how to connect to an endpoint falls into one of the following categories:.
Protocols Determines the security mechanism being used: either reliable messaging capability or transaction context flow settings. A binding basically consists of an ordered stack of binding elements, each of which specifies part of the communication information required to connect to a service endpoint. The two lowest layers in the stack are both required. At the base of the stack is the transport binding element and just above this is the element that contains the message encoding specifications.
The optional binding elements that specify the other communication protocols are layered above these two required elements. For more information about these binding elements and their correct ordering, see Custom Bindings. The information in a binding can be complex, and some settings may not be compatible with others. For this reason, WCF includes a set of system-provided bindings. These bindings are designed to cover most application requirements. The following classes represent some examples of system-provided bindings:.
