In the previous chapter, we introduced the basic knowledge of WCF binding. In this chapter, we use a demo to introduce how to create a custom binding (custombinding)Program. In this chapter, we assume that you have a fixed understanding of WCF. The demo creation process will omit some simple steps. The difference between custom binding and the previously introduced WCF program is that you can modify the configuration file to create custom binding.

Introduction
Essentially, WCF is a communication service framework that allows us to use different transmission protocols and different message encoding formats to interact with different WS-* series standards, all these details are handled by the channel stack. In the WCF topic series (8): Deep Channel Programming Model Part 1-design, I have a deep understanding of the channel model in WCF. In this article, I will explain through examples how the server receives messages and how the client send
binding httptransportbindingelement (); CustomBinding (bindingelements); HttpTransportBindingElement is added here, so the generated channel stack has an HTTP transport channel, and a text message encoder is also used. Next Call the CustomBinding Buildchannellistener method you just created to construct the channel listener, you need to specify the listening base address and binding parameters, and

In addition, you also need to determine the point of the application server.
The configuration example is as follows:

Add key = " cslaauthentication " value =" csla "/>
Add Key="Csladataportalproxy"Value="Csla. dataportalclient. wcfproxy, csla"/>

The datagram mode refers to the method in which the sender sends the message to the other party and completes interaction after receiving the confirmation message. The sender only determines that the message is successfully sent, however, I do not know whether the message has reached the final node, whether it has been processed, and how the returned results are completely unknown;
The client implements the ioutputchannel, and the server implements the iinputchannel

WCF configuration scenario. Reference address 1 resolves how the WSDL address generates a client-callable. cs file through the WCF tools.Operation Steps:
Open the Developer Command prompt tool for VS 2017
Enter SvcUtil.exe http://localhost:6054/ServiceDemo.svc?wsdl, and a direct carriage return will generate two files. cs,. config.
. cs files are copied directly into the project, and. config is changed to your project's app. config replacement. Open App. Config fileXML version= "1.0"

The most common change is to increase the idle timeout to better match the session expiration rules.Standard bindings:Some standard bindings support reliable sessions, especially nettcpbinding,wshttpbinding and wsdualhttpbinding.Wsdualhttpbinding reliable sessions are always available, and you cannot turn them off.NETTCPBINDING,WSHTTPBINDING2 bindings can be declared to support reliable sessions, which need to be added to the As shown
1. Create a custom binding
Sometimes we need to create our own binding, which is not due to special security requirements and transmission protocols used in many cases. To create a custom binding, you need to create a group of binding elements. The binding element is derived from System. ServiceModel. Channels. BindingElement.
Code 1: custom binding using HTTP transmission protocol and Binary encoding format:
In addition to creating a custom binding by configuration, you can also use program

If there are a lot of errors during the loading of WCF, it is basically a reference problem. It is better to let vs generate a reference list by itself. So first add a Silverlight enabled WCF -- call temp, and then delete it, And the ref will be d

Then I checked it carefully, I found that the binding of the final point of the WCF Service released by my server is wshttpbinding, while the binding configured for the SL client proxy class is custombinding, which is indeed inconsistent, however, it seems that the sl3.0 client configuration does not support W Shttpbinding seems to support only custombinding and basichttpbinding, so I
