Why wcf services are used

NET remoting service can be consumed only by another. NET application. The first client is using a Java application to interact with our services. The second Client is using. NET and for better performance, this client wants a message format in binary format and protocol to be in TCP. Without WCF, to satisfy the second client requirement, we will create a.

NET Remoting service. Therefore, developers have to learn two different technologies, which is not only time and cost consuming but needs two people with expertise. A loosely-coupled relationship implies that any client created on any platform can connect to any service as long as the essential contracts are met. WCF implements modern industry standards for Web service interoperability.

For more information about the supported standards, see Interoperability and Integration. Messages are exchanged in one of several patterns. The second endpoint replies.

There are other patterns such as a one-way message in which a single endpoint sends a message without any expectation of a reply. A more complex pattern is the duplex exchange pattern where two endpoints establish a connection and send data back and forth, similar to an instant messaging program. For more information about how to implement different message exchange patterns using WCF see Contracts.

This metadata can be used to automatically generate and configure clients for accessing WCF services. For more information, see Metadata. Because WCF is built using the. NET Framework, it also includes code-friendly methods of supplying the contracts you want to enforce.

One of the universal types of contracts is the data contract. In essence, as you code your service using Visual C or Visual Basic, the easiest way to handle data is by creating classes that represent a data entity with properties that belong to the data entity. WCF includes a comprehensive system for working with data in this easy manner.

Once you have created the classes that represent data, your service automatically generates the metadata that allows clients to comply with the data types you have designed. For more information, see Using Data Contracts.

By default Header and fault are disabled but Body is responsible for the data transmission or data exchanging. Header is useful to send some data from client to Server. Endpoint is a very essential part of WCF Application, as it describes the address of Web Service from where a user can receive and send the message. It also specifies the communication mechanism of how the message will be sent or received.

What is WCF. Asit Singh Updated date Mar 13, There are so many reasons for it but now I am giving you an answer in two words- one is protocol and the other is hosting. Thus, I will explain these two words later in this article. It means that an Application can consume or connect with another Application but it does not matter in which platform it is developed.

It is mainly part of the. Net framework. It is used for developing service-oriented applications. It is used to create and consume services. WCF provides the platform for building and deploying various distributed network services. WCF service is easy to use, and it is flexible as well.

This service can be hosted in IIS, self-hosting, and windows activation service. It is a service that helps in message exchange in XML format using HTTP protocol for interoperability, and it also acts as a remoting service to exchange the message in binary format using TCP protocol for performance.

WCF service helps in communicating with the people or exchanging the data with the help of chat. It supplies the data to monitor the service like a traffic report.
