Why wcf is required

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. Web Service is interoperable because it can be consume from any client, either it is from Java or.

NET but on a remote basis, it is not interoperable because if we want to consume any remote service from the client, client Application must be developed in.

Suppose, you have two clients- one wants to use a Web Service, which sends data over the network, using Http protocol and want reply in XML format, so we will create a Web Service. The other wants to send the data, using Web Service over the network, using TCP protocol and replying in binary format, then we need to implement a remote Web service with TCP protocol.

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. CoreWCF has active community involvement and has been updated regularly since its creation. It is still WCF. CoreWCF is a. NET 5 applications that need to interact with. NET Framework applications can use this as an option that will feel native to both. It is not ready for production. According to the. NET Framework team, this project requires community time and testing to get it into shape. There is no guarantee that it will ever get to the point where it will be considered good enough for production.

It is not intended to be a complete port. This is a smart approach, as it means they will spend the most effort on functions that benefit the most users. But if you are using parts of WCF outside the scope of this project, you may need to find another solution anyway. At this point, there are just better solutions to the problems it set out to solve.

CoreWCF is convenient because it may allow you to make the least amount of changes to your application to use. NET 5, but is it the best choice? Easy Browser Interaction. This is an actively developed component of the. It has full support from Microsoft and a large community of users. A good choice if you have a public API. It will be easier for everyone to work with.

You miss out on some of the performance benefits of gRPC. This causes a performance gap that cannot be realistically crossed. Not built for long-lived connections. This is good for things like messages, notifications, or sending large datasets over a connection one element at a time. If you are looking for a flexible framework, target gRPC gRPC is already used in many cross-platform applications and across multiple frameworks as well.

If your application interacts primarily with the browser, target ASP. It has some downsides compared to gRPC, but it is much easier to work with for web applications.

It is mainly used for building SOAP services. It is very secured and used the data to show in logical representation. It is one of the good services to be used than web service. It is flexible and provides many features for developing the service, and easy to consume as well. Its architecture is not complex. The programmers used this service because of its features and advantages that are mentioned above.

This has been a guide to What is WCF. Here we discussed the Basic concepts, working, and architecture with the advantage of WCF. You can also go through our other suggested articles to learn more —. Submit Next Question.
