What is WCF used for?

Windows Communication Foundation (WCF) is a framework for building service-oriented applications. 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.

How does WCF binding work?

What WCF Binding is

1. basicHttpBinding: This binding works only on http protocol.
2. wsHttpBinding: This binding basically does what basicHttpBinding does, but difference is this binding implements ws-* specification.
3. NetNamedPipeBinding: This binding provide cross process communication on the same machine.

What is WCF binding and how many of them do you know?

WCF binding is a set of binding elements and each element specify, how the service and client will communicates with each other’s. Each binding must have at least one transport element and one message encoding element.

What is WCF and its advantages?

Advantages of WCF WCF provides better reliability and security compared to ASMX Web services. In WCF, there is no need to make much of a change to code to use the security model and alter the binding. Small changes in the configuration file will match your requirements. WCF provides interoperability between services.

When should I use WCF?

WCF is useful when building applications or services that need to communicate with each other. You can use WCF to easily build programs that communicate, whether it’s across processes, across servers, or across the world.

How many types of binding are there in WCF?

You can define bindings in two ways: through code or through configuration. These two approaches do not depend on whether you are using a system-provided binding or a custom binding.

What are different types of binding in WCF?

Various Types of Bindings WCF Supports

• Basic binding. This binding is provided by the BasicHttpBinding class.
• Web binding. This binding is provided by the WebHttpBinding class.
• Web Service (WS) binding.
• TCP binding.
• IPC binding.
• MSMQ binding.
• Federated WS binding.
• Peer Network binding.

What protocol does WCF use?

The protocols that are typically used in this channel are HTTP, TCP, MSMQ, and named pipes, but WCF allows application developers to use other transports as well, such as Simple Mail Transfer Protocol (SMTP) or File Transfer Protocol (FTP).

What are the features of WCF?

The features of WCF are mentioned below:

• It supports service-oriented architecture.
• It supports multiple transport and encoding.
• Multiple message patterns.
• Data contracts.
• Service Metadata.
• Durable messages.
• Reliable and Queued messages.
• Ajax and Rest Support.

What do you need to know about WCF service binding?

WCF – Service Binding. WCF service binding is a set of several elements in which each element defines the way the service is communicating with the client. A transport element and a message encoding element are the two most vital components of each binding. In this chapter, we will discuss various WCF service bindings that are commonly used.

How are bindings used in Windows Communication Foundation?

Windows Communication Foundation (WCF) separates how the software for an application is written from how it communicates with other software. Bindings are used to specify the transport, encoding, and protocol details required for clients and services to communicate with each other.

What do you need to know about WCF and TCP?

WCF lets you choose HTTP or TCP transport protocol, encoding, etc. just by tweaking the value of binding attribute for an endpoint. To cater to different transport protocols, WCF lets you select HTTP, TCP and MSMQ binding types.

Which is the fastest WCF binding for intra-server communication?

It less inter-operable, but using binary encoding which is faster. Use named pipe binding for intra-server communication, that is for consumers hosted in same servers. Named pipe binding is the fastest one in wcf allowed bindings.
