Windows Hosting in WCF

File-new Project-windows Service

Next Right Click on Add Installer

We have to add the reference of our WCF Service Library DLL in this service.

To do this, right click on the project in Solution Explorer and select Add Reference. For adding the dll in reference, select browse tab in the window that appears, and navigate to the folder where our WCF service library is located. In that location, the dll can be found inside the bin-> debug folder. When this dll is added, it is imported into the Windows service app.

Similarly we need reference of System.ServiceModel namespace because it is not available by default in Windows Service.

We will get two processes

Service process installer

Service installer

Service.cs

public partial class Service1 : ServiceBase

    {

        ServiceHost sHost;

        public Service1()

        {

            InitializeComponent();

        }

        protected override void OnStart(string[] args)

        {

            sHost = new ServiceHost(typeof(WcfServiceLibrary3.Jobs));

            sHost.Open();

        }

        protected override void OnStop()

        {

            sHost.Close();

        }

    }

Registering the Service with Windows OS

Go to the design view of the Windows service, right click and click on Add Installer option.

When this is clicked, we get two processes – ServiceProcessInstaller and ServiceInstaller.

Click on ServiceProcessInstaller and set its account property to local system.

Now click on Service Installer properties

Now build the service once again. This will create an executable file.

Copy the path of this exe file location and open the containing folder from command prompt.

In that path write the command

InstallUtil WindowsService.exe

Which registers the service with Windows OS?

Once it is registered with Windows, we can see it in the services list.
