What is WCF

WPF offers developers 2D and 3D graphics support, hardware-accelerated effects, scalability to different form factors, interactive data visualization, and superior content readability. Windows Communication Foundation (WCF) Windows Communication Foundation (WCF) is Microsoft’s unified programming model for building service-oriented applications. WPF offers developers 2D and 3D graphics support, hardware-accelerated effects, scalability to different form factors, interactive data visualization, and superior content readability. Windows Communication Foundation (WCF) is Microsoft’s unified programming model for building service-oriented applications.

In this article, I will explain the difference between ASP. NET web services. I will also discuss how we use both the technologies for developing the web services. A Web Service is programmable application logic accessible via standard Web protocols.

Using WCF, you can send data as asynchronous messages from one service endpoint to another. A service endpoint can be part of a continuously available service hosted by IIS, or it can be a service hosted in an application. An endpoint can be a client of a service that requests data from a service endpoint. The messages can be as simple as a single character or word sent as XML, or as complex as a stream of binary data.

WCF is a replacement for all earlier web service technologies from Microsoft. It also does a lot more than what is traditionally considered as "web services". You will get a much higher degree of flexibility and portability doing things in WCF how to write discussion chapter in phd thesis through traditional ASMX because WCF is designed, from the ground up, to summarize all of the different distributed programming infrastructures offered by Microsoft.

In theory, this reduces the amount of new code needed when porting or changing business needs, targets, etc. Basically you can see WCF as trying to logically group together all the different ways of getting two apps to communicate in the world of Microsoft; ASMX was just one of these many ways and so is now grouped under the WCF umbrella of capabilities. The development of web service with ASP. NET relies on defining data and relies on the XmlSerializer to transform data to or from a service.

The DataContractAttribute can be applied to the class or a strcture. DataMemberAttribute can be applied to field or a property and theses fields or properties can be either public or private. To develop a service using ASP. The ServiceContractAttribute specifies that an interface defines a WCF service contract, OperationContract attribute indicates which of the methods of the interface defines the operations of the service contract. NET web services are compiled into a class library assembly and a service file with an extension.

The service file is copied into the root of the ASP. NET application and Assembly will be copied to the bin directory. The application is accessible using URL of the service file. Clients for the ASP. WCF uses the ServiceMetadata tool svcutil. It returns the WSDL as a response to the request.

But if you have an API exposed to receive two numbers and return result over httpthen it should be called a web service. At low level, both Web application and web service are kind of same thing.

Background

WPF = Windows PRESENTATION Foundation. WCF deals with communication (in simple terms - sending and receiving data as well as formatting and serialization involved), WPF deals with presentation (UI) WCF: WCF stands for Windows Communication Foundation. It is used to create a distributed and interoperable Applications. Dec 10,  · Choosing between WCF vs. WPF Application WCF is Microsoft’s integrated programming model that is utilized for the creation of service-oriented applications. By way of WCF Application, developers. Aug 28,  · WCF might be used if your application needs to provide or consume data from some other completely separate application (typically over the internet). For example, if your accounting application needed to exchange data with your inventory application; or if your weather widget consumes data published by NOAA. WPF is Windows Presentation Foundation.

It is basically used to create a distributed and interoperable Application. WCF Applications came into the picture in. Net 3. This is a framework, which is used for creating Service oriented Applications. You can send the data asynchronously from one end point to another. I think you all know about Web Service and are thinking, if we already have Web Services and accessing on a remote basis then why did WCF come into picture? Distributed Application It means those Applications, which do not run only on single system but can run on multiple systems, which are connected over the network.

For example, a Web Service that can consume by different clients. 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. 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.

The problem is in the example, shown above, we need to create two different Services for two different clients. WCF is solving this problem and one single service can be consumed by two different clients- either they want same protocol or a different protocol. We specify the protocol name in an endpoint attribute of the Web Service. Service Client: Who is the client of the Service. Fundamentals of WCF Message. Message is the communication unit, as it is in the form of an envelop.

The transmission of the data from the client to Service and Service to client is being done by envelop. The envelop or message has the sections, given below-. Header Body. It describes the way or mechanism by which the user will communicate with Web Service. Message format or security techniques etc.

Contract is the third important question. What functionality and operation is being provided by the service is called contract. It specifies what functionality and operations are need to be exposed to the client.

It is the interface name which has all operation that need to be exposed. It is not a transport protocol but an XML based message protocol.
