Today, I would like to talk to you about how to understand ASP.NET 3.5 WCF services. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.

ASP.NET 3.5 WCF Service

In the past few years, Web services have been doing a lot of publicity, claiming to provide cross-platform services. The implementation proves that Web services do support the use of clients and servers on different platforms. In addition, by defining a WSDL contract, you can plan version changes in advance, effectively avoiding possible crashes of existing clients and servers. At present, Microsoft ASP.NET is one of the important technologies used to develop Web services. The wide application of Web services on ASP.NET and JAVA platforms is a strong evidence of the vitality of Web services technology.

However, the problem in ASP.NET Web service is that it uses HTTP protocol (through WSE 2.0, you can also use TCP channel), the speed of XML serialization with SOAP protocol is not fast enough, and some extension functions are difficult to use. Web services technology has indeed taken an important step in providing cross-platform services, but it has been quite difficult to rely on Web services alone in establishing interoperable services involving licensing, ensuring message transmission, platform-independent authentication, authorization and confidentiality.

With the official launch of the .NET 3.0 framework, WCF (the Foundation of Windows Communications) made its debut. The core purpose of WCF is to allow programs to communicate with other programs on the same computer or network or across the Internet. This model unifies the four important technologies of using services on the network, namely, Web services,. Net remote technology, distributed transactions and message queues, into a single service-oriented programming model, so as to realize the real distributed computing. WCF represents the future development direction of Microsoft communication technology. Therefore, in principle, any development that needs to use the above four technologies can use WCF instead.

However, it is impossible for developers to choose all WCF communication technologies in real Web development environment. In other words, applications based on ASP.NET 2.0 Web services technology will still have a considerable market share in the next few years.

The ASP.NET AJAX framework greatly simplifies the operation of invoking local services and even remote services from ASP.NET applications, and even provides many built-in server services, such as user authentication services and user personalization services.

[note] prior to the .NET Framework 3.5, there was no built-in support for JSON data in WCF. Today, with the official launch of the .NET Framework 3.5, WCF has implemented support for serialization and non-serialization of JSON. Today's WCF services can selectively output JSON according to development needs, rather than data that only supports SOAP schema encapsulation as before.

After reading the above, do you have any further understanding of how to understand ASP.NET 3.5 WCF services? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
