Steps for a simple WCF Service with netTCPBinding hosted in a Windows Service

Microsoft – How to: Host WCF in a Windows Service Using TCP

Create a new project with a WCF Service Library

Rename the default classes

Change ServiceContract

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace WcfHelloWorldService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IWcfHelloWorld
    {
        [OperationContract]
        string HelloWorld(string name);
     
    }
}

Change Method

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace WcfHelloWorldService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in both code and config file together.
    public class WcfHelloWorld : IWcfHelloWorld
    {
        public string HelloWorld(string name)
        {
            return string.Format("Hello {0}", name);
        }


       
    }
}

Configure the config to use net

Name the Service Behavior to WcfHelloWorldService.WcfHelloWorldServiceBehavior

Set GetEnabled to false

Select the Behavior Configuration name

Build the project

Create a Windows Service to host the WCF Service

Delete Service.cs

Add a Windows Service called WcfHelloWorldService.cs

Make sure Program.cs is instantiating the Service just created

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Threading.Tasks;

namespace WcfHelloWorldServiceHost
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        static void Main()
        {
            ServiceBase[] ServicesToRun;
            ServicesToRun = new ServiceBase[] 
            { 
                new  WcfHelloWorldServiceHost.WcfHelloWorldService()  //the windows service
            };
            ServiceBase.Run(ServicesToRun);
        }
    }
}

Add references to the newly created WCF Service and System.ServiceModel

Change the code in WcfHelloWorldService.cs to the code below

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Threading.Tasks;
using System.ServiceModel;
using WcfHelloWorldService;

namespace WcfHelloWorldServiceHost
{
    partial class WcfHelloWorldService : ServiceBase
    {
        internal static ServiceHost myServiceHost = null; //declare a service host
        public WcfHelloWorldService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            if (myServiceHost != null)
            {
                myServiceHost.Close();
            }
            myServiceHost = new ServiceHost(typeof(WcfHelloWorld));//service host of the scf service
            myServiceHost.Open();
        }
        protected override void OnStop()
        {
            if (myServiceHost != null)
            {
                myServiceHost.Close();  //close the host
                myServiceHost = null;
            }
        }

    }
}
