This article mainly shows you "what are the benefits of using WCF", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "what are the benefits of using WCF" this article.

Under the Windows platform, especially under the .NET platform, to develop service-oriented applications, or develop distributed systems, the choice is WCF. Why?

The reason is that WCF covers all the technologies previously introduced by Microsoft for distributed development, including Remoting, Web Services, WSE, MSMQ and so on, and is implemented in a unified programming mode. WCF benefits: WCF not only supports interoperable Web services, but also enables communication between .NET clients and .NET servers, provides support for distributed transactions, and fully complies with WS-* standards in terms of security. In addition, it also supports queuing services, which can easily use message queues to complete asynchronous operations and offline calls. And these functions, the previous technology is only part of the implementation. As shown in the following table:

The benefits of WCF: WCF also makes service-oriented programming easier and more unified. If the old technology is used, because the programming models of various technologies are completely inconsistent, the migration of the program is very difficult. For example, a distributed system originally developed using .NET Remoting technology requires the release of interoperable Web services due to changes in business requirements, which requires redefinition of services. In addition, the way the client is called has also changed, and you need to add a Web reference to discover the service through UDDI.

WCF is not the case. WCF introduces the usage channel, which encapsulates the communication details of the message, such as coding, transaction processing, security, etc., and then encapsulates the composition order and processing details of the channel by introducing the concept of binding. *, a unique Endpoint element is introduced, which integrates the "trinity" of address, binding and contract to define and publish services in the simplest way.

The above is all the contents of the article "what are the benefits of using WCF?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
