This article introduces you how to understand WCF ServiceContract features, the content is very detailed, interested friends can use for reference, I hope it can be helpful to you.

If you want to make good use of a technology, you need to understand its basic features, such as the properties of a class. Let's analyze the WCF ServiceContract features. Windows Communication Foundation (Windows Communication Foundation,WCF) is a software development kit (Software Development Kit,SDK) based on the development and deployment of services under the Windows platform.

WCF provides a run-time environment (Runtime Environment) for services, allowing developers to expose CLR types as services and to use services as CLR types. In theory, WCF is not necessarily required to create a service, but in practice, using WCF can make the task of creating a service twice the result with half the effort. WCF is Microsoft's implementation of a range of industry standard definitions, including service interaction, type conversion, Marshaling, and the management of various protocols. Because of this, WCF is able to provide interoperability between services. The WCF ServiceContract feature allows you to apply to an interface or class. When the Service-Contract feature is applied to the interface, you need to define a class to implement the interface. In general, we can use C # or VB to implement the interface, and the code of the service class does not need to be modified, so it naturally becomes a WCF service:

[ServiceContract] interface IMyContract {[OperationContract] string MyMethod ();} class MyService: IMyContract {public string MyMethod () {return "Hello WCF";}}

We can implement the interface implicitly or explicitly:

Class MyService: IMyContract {string IMyContract.MyMethod () {return "Hello WCF";}}

A single class can support multiple contracts by inheriting and implementing multiple interfaces marked with WCF ServiceContract features.

[ServiceContract] interface IMyContract {[OperationContract] string MyMethod ();} [ServiceContract] interface IMyOtherContract {[OperationContract] void MyOtherMethod ();} class MyService: IMyContract,IMyOtherContract {public string MyMethod () {.} public void MyOtherMethod () {.}}

However, the service class also has some implementation constraints. We should avoid using parameterized constructors because WCF can only use the default constructor. Similarly, although classes can use internal (internal) properties, indexers, and static members, WCF clients cannot access them.

On how to understand WCF ServiceContract features to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
