Windows Communication Foundation (WCF) is a framework for building service-oriented applications. Using WCF, you can send data as asynchronous messages from one. This article concentrates on building the Web Service from scratch using HttpHandlers, and will give a detailed understanding of operations that happen “under the. What Is Windows Communication Foundation. Windows Communication Foundation (WCF) is a framework for building service- oriented applications. Developing and deploying a Windows Communication Foundation (WCF) service that is hosted in Internet Information Services (IIS) consists of the following tasks. I m getting the following error when I did set the Windows Authentication enable and anonymous to disabled in IIS. The authentication schemes configured on the host. Web + Mobile. Web + Mobile; App Service Quickly create powerful cloud apps for web and mobile. Immerse yourself in a virtual hands-on lab and experience the product first hand, or try our guided experiences, and click through a tour of the various product features. HBO is employing feelings-measuring technology to establish the emotional reactions that are generated. Tips for buying: You may buy without logging in, however to provide a better service we suggest to login. License/Pricing details. 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. A few sample scenarios include: A secure service to process business transactions. In summary, WCF is designed to offer a manageable approach to creating Web services and Web service clients. For more information, see WCF Feature Details. Service- oriented architecture (SOA) is the reliance on Web services to send and receive data. The services have the general advantage of being loosely- coupled instead of hard- coded from one application to another. 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. For more information about the supported standards, see Interoperability and Integration. The most common pattern is the request/reply pattern, where one endpoint requests data from a second endpoint. 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. Metadata can be published over HTTP and HTTPS or using the Web Service Metadata Exchange standard. For more information, see Metadata. 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. Security Messages can be encrypted to protect privacy and you can require users to authenticate themselves before being allowed to receive messages. Security can be implemented using well- known standards such as SSL or WS- Secure. Conversation. For more information, see Security. The most common protocol and encoding is to send text encoded SOAP messages using is the Hyper. Text Transfer Protocol (HTTP) for use on the World Wide Web. Alternatively, WCF allows you to send messages over TCP, named pipes, or MSMQ. These messages can be encoded as text or using an optimized binary format. If none of the provided transports or encodings suit your needs you can create your own custom transport or encoding. For more information about transports and encodings supported by WCF see Transports. For more information about reliable and queued messaging support in WCF see Queues and Reliable Sessions. The messages in a durable message pattern are always saved to a database. If a disruption occurs, the database allows you to resume the message exchange when the connection is restored. You can also create a durable message using the Windows Workflow Foundation (WF). For more information, see Workflow Services. For more information about transaction support in WCF see Transactions. WCF can be configured to process . WCF can also be extended to support specific XML formats, such as ATOM (a popular RSS standard), and even non- XML formats, such as Java. Script Object Notation (JSON). If extra capability is required, there are a number of entry points that allow you to customize the behavior of a service. For more information about available extensibility points see Extending WCF. Because of this extreme flexibility, WCF is also used in several other Microsoft products. By understanding the basics of WCF, you have an immediate advantage if you also use any of these products. Workflows simplify application development by encapsulating steps in the workflow as . The next version of Windows Workflow Foundation was integrated with WCF. That allowed any workflow to be easily hosted in a WCF service; you can do this by automatically choosing the WF/WCF a project type in Visual Studio 2. Biz. Talk is designed to receive and transform data from one standardized format to another. Messages must be delivered to its central message box where the message can be transformed using either a strict mapping or by using one of the Biz. Talk features such as its workflow engine. Biz. Talk can now use the WCF Line of Business (LOB) adapter to deliver messages to the message box. Beginning with version 2, Silverlight has incorporated WCF as a communication technology to connect Silverlight applications to WCF endpoints. The hosting features includes rich tooling and configuration options specifically designed for WCF- enabled applications.
