Using the Open () and Close () methods provided by ServiceHost provided by WCF, it is convenient for developers to host services in console applications, Windows applications, and even ASP.NET applications. The way services are hosted is essentially the same regardless of the application in the home-hosting environment. For example, in a console application:

Using (ServiceHost host = new ServiceHost (typeof (DocumentsExplorerService) {host.Open (); Console.WriteLine ("The Service had been launched."); Console.Read ();}

The ServiceHost instance is created in the application domain, so we must ensure that the host process is not shut down during service invocation, so we use Console.Read () to block the process so that the console application can keep running until the application is presumably closed. If it is a Windows application, you can place the code that creates the ServiceHost instance in the relevant code of the main form to ensure that the service WCF self-managed host will not be closed. Accordingly, we need to configure the application's app.config configuration file:

Note that the service name in the configuration file must contain the service contract and the namespace of the service class. In addition, I added the base address to the service through the tag in the configuration file, so in endpoint, address is "".
