WSHttpBinding It is more secure, reliable and interoperable as compared to basic http binding. Duplex is a message pattern that is used by client and service to exchange their message via callback. In this binding reliable sessions are enabled by default. WSFederationHttpBinding Sometimes we need to add federated security service which helps us to implement federation which has the ability to share identities with multiple domains for authentication and authorization.
It uses WS-federation protocol. It provides cross machine communication and supports WS-ReliableMessaging by default. It provides more secure transfer and reliable communication. It also uses WS-ReliableMessaging for secure transfer of data over the network and delivering the data in binary encoding.
NetMsmqBinding It is used for queue communication. It means that this binding gives us secure and reliable queued communication for the cross machine environment. By default it creates communication stack using WS-ReliableMessaging protocol for reliability, TCP for message delivery and windows security for message and authentication at run time. It uses TCP protocol and provides support for security, transaction and reliability.
This binding provides secure and reliable binding environment for on-machine cross process communication. By default it creates communication stack with WS-ReliableMessaging for reliability, transport security for transfer security, named pipes for message delivery and binary encoding. WSHttpBinding Defines a secure, reliable, interoperable binding suitable for non-duplex service contracts.
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:. NET Web services-based services.
NetNamedPipeBinding : Uses the. NetNamedPipeBinding has Support for duplex communication mode and also transactions support. Secure, reliable and transaction supported. There are Supports for the duplex mode of communication. Net 3. Thus, in. Net version 3. Net Remoting model. Depending upon your requirements, you can choose a binding most suitable for you. Here is a flow chart that will assist you in choosing appropriate WCF binding for your application. Image Credit: mohammedatef.
In this article, we covered basics of WCF Bindings. We hope this article helped you to get an idea of different WCF Bindings. Here we tried to explain different WCF bindings supported by WCF in very simple terms for the understanding of beginners also.
