Notify the client of the result of one-way operation using the callback contract
Use callback contract to implement event mechanism
A callback contract is used to notify the client of the results of one-way operations. A callback contract is used to provide a service that notifies the client of one-way operations without returning any information.
Program . The example in this section is based on the previous product price change scenario. When the client progra

We all know that the data contract is also server-side to client serialization and deserialization, such serialization is similar to the ASP.net ajax access WebService. ASP.net ajax Typically, the server-side data is serialized into a Jason string passed to the foreground script, but we might want to control some data contracts fil

6. Deploy the WCF Service Program to three PCs in the LAN
To remotely deploy a WCF Service program, you need to relocate its config configuration file, and change the default IP address 127.0.0.1: 5600 to the IP address of the remote computer:
10.92.202.56: 5600, 10.92.202.57: 5700, 10.92.202.58: 5800
Then start the remote computer's
the message header and body, that is, to determine whether to digitally sign and encrypt these elements. Message-style operations provide such control.
Create a Message Protocol
A message style operation can have a maximum of one parameter and one return value. Both the parameter and return value types are message types. That is, these two types can be directly serialized into the specified SOAP message structure. This can be any type or Message type marked with MessageContractAttribute.
