Wcf how many endpoints

An address is the endpoint location that provides the service to the outer world especially its clients using a network protocol. The address is usually in the form of an URL.

WCF bindings represent a collection of elements, which will describe the various aspects of communication between a service and its clients. Its three main characteristics are,. An optional feature, a protocol defines information related to security , reliability and transaction flow of the message. It will define the means for transporting message from service endpoint to a client endpoint. This feature is required to specify the encoding of the message, which can be either a Text or Binary message.

We will discuss few binding types in this article. Before WCF services took over,. Net developers commonly used ASMX services. HTTP is the transport protocol used for this type of binding.

It typically uses an encoder to encode SOAP messages. By default, this binding does not provide any security , due to its interoperability feature, and hence disabled.

We need to configure the security mode explicitly in the web. To see how to configure the security mode, open the web. Hence, it is limited to newer versions only, that is, services created using wsHttpBinding will not support clients using older. Net versions. Create a free Team What is Teams?

Some things to note: The binding is typically going to be a combination of channels with behaviors applied; channels being elements on the channel stack which modify the message and perform actions before they get to the service implementation. Improve this answer. Each Endpoint is a portal for communicating with the world. All the WCF communications are take place through end point.

End point consists of three components. Client will use this url to connect to the service. These endpoints can use the same or different bindings and can expose the same or different contracts. There is absolutely no relationship between the various endpoints a service provides. It is important to point out that nothing in the service code pertains to its endpoints, and they are always external to the service code.

You can configure endpoints either administratively using a config file or programmatically. Configuring an endpoint administratively requires placing the endpoint details in the hosting process config file.

For example, given this service definition:. Example shows the required entries in the config file. Under each service type, you list its endpoints.

When you specify the service and the contract type, you need to use fully qualified type names. I will omit the namespace in the examples throughout the remainder of this book, but you should use a namespace when applicable. A mismatch causes an exception at service load time. Example shows a config file defining a single service that exposes multiple endpoints.

You can configure multiple endpoints with the same base address as long as the URI is different. Administrative configuration is the option of choice in the majority of cases because it provides the flexibility to change the service address, binding, and even exposed contracts without rebuilding and redeploying the service. In Example , each endpoint provided its own base address. When you provide an explicit base address, it overrides any base address the host may have provided.

You can also have multiple endpoints use the same base address, as long as the endpoint addresses differ in their URIs:. Alternatively, if the host provides a base address with a matching transport scheme, you can leave out the address.

In this case, the endpoint address will be the same as the base address of the matching transport:. If the host does not provide a matching base address, loading the service host will fail with an exception.

When you configure the endpoint address, you can add just the relative URI under the base address:. The endpoint address in this case will be the matching base address plus the URI and, again, the host must provide a matching base address.
