Use WCF's duplex service to push messages to WinForm programs

First look at the running effect: send a message "like" in the Web page, use WCF's duplex service to push messages to the WinForm program, WinForm end receive messages,

Create two projects, a WebForm project and a WinForm project, and build the files you need under the project

Sendmessage.aspx is a Web page that sends messages

ISendMessageService.cs and sendmessageservice.svc are used to implement WCF duplex services

GetMessageForm.cs is the WinForm window for receiving messages

Of course, you also need to create a message entity file: MessageEntity.cs, for simplicity, just define a property for him.

[DataContract]
　　　　public　class　 MessageEntity
　　　　{
　　　　　　　　[DataMember]
　 　　　　　　　public　string　Content　{　get;　set;　}
　　　　}
