This article mainly introduces "WCF performance example Analysis". In daily operation, I believe many people have doubts about WCF performance example analysis. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "WCF performance example Analysis". Next, please follow the editor to study!

WCF (Windows Communication Foundation), as a new generation of framework product under the. Net platform launched by Microsoft based on SOA, integrates the advantages of existing technologies and represents the development direction of future software architecture design and development. Therefore, it is very necessary for programmers, especially those based on Microsoft technology, to master and make rational use of WCF technology in future applications. Based on this, this paper introduces a set of specific development process of instant messaging software to show the basic steps and advanced skills of distributed software development based on WCF technology.

For a good distributed system, heterogeneity, openness, security, scalability, fault handling, concurrency and transparency should be taken into account in design. Web Service based on SOAP can achieve interoperability in heterogeneous environments and ensure cross-platform communication. Using WSE (Web Service Enhancements) can provide security guarantee for ASMX. The .NET Remoting has rich extension capabilities to create custom channels, formatters, and agents. Enterprise Service (COM+) provides support for transactions, including distributed transactions, for failure recovery.

MSMQ can support asynchronous calls, offline connections, breakpoint connections and other functions, using message queuing to support message delivery between applications. From a functional point of view, WCF integrates the advantages of existing technologies such as ASMX, .net Remoting, Enterprise Service, WSE and MSMQ. It provides a unified framework model for building secure and reliable distributed service-oriented systems, which makes it easier for software developers to develop distributed applications.

1. Service oriented

Since WCF performance is a service-oriented framework, services are naturally the most important concept in WCF. Service refers to a collection of exposed functions, while service orientation refers to a set of abstract principles and methods for building "service-oriented programs". For the understanding of business logic, the traditional programming way is that business logic should be encapsulated as an object, which provides some business-related functions, while WCF-based programming is more concerned about how to provide services and consume services. Similar to component-oriented service programs, SOA-based applications encapsulate services into a single logical program, as shown in figure 1.

2.WCF performance architecture

WCF has a very flexible hierarchical architecture, and distributed applications can be written using either high-level API or low-level API. The advanced API or service layer can be used to invoke methods and events. The service layer converts these high-level abstract code into messages to use the channels and ports on the low-level API. The layers of the WCF application are shown in figure 2.

At this point, the study of "WCF performance example Analysis" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
