WCF using windows service

Question

I am creating a WCF service that will be hosted in a Windows service. I created a console application as follows

I went to the management console (services.msc) and started the service. But I got the following error:

The LijosWindowsService service on the local computer started and then stopped. Some services stop automatically if they do not have work, for example, performance logs and alerts

I went to the event viewer and got the following

The service cannot be started. System.InvalidOperationException: The Lijo.Samples.WeatherService service has a null application (no infrastructure). This is possible, due to the lack of a configuration file was found for your application or because no mapping of service items to the service name can be found in the configuration file, or because no endpoints were defined in the service item.

Could you tell me what is missing here?

File Name [LijosService.cs]

using System.ComponentModel;
using System.ServiceModel;
using System.ServiceProcess;
using System.Configuration;
using System.Configuration.Install;

namespace Lijo.Samples
{
   [ServiceContract(Namespace = "http://Lijo.Samples")]
   public interface IWeather
   {
      [OperationContract]
      double Add(double n1, double n2);
   }

   public class WeatherService : IWeather
   {
       public double Add(double n1, double n2)
       {
           double result = n1 + n2;
           return result;
       }
   }

   public class MyWindowsService : ServiceBase
   {
       public ServiceHost serviceHost = null;

       public MyWindowsService()
       {
           // Windows Service name
           ServiceName = "LijosWindowsService";
       }

       public static void Main()
       {
           ServiceBase.Run(new MyWindowsService());
       }

       protected override void OnStart(string[] args)
       {
           if (serviceHost != null)
           {
               serviceHost.Close();
           }
           serviceHost = new ServiceHost(typeof(WeatherService));
           serviceHost.Open();
       }

       protected override void OnStop()
       {
           if (serviceHost != null)
           {

               serviceHost = null;
           }
       }
   }

        {
            myProcess = new ServiceProcessInstaller();
            myProcess.Account = ServiceAccount.LocalSystem;

            myService = new ServiceInstaller();
            myService.ServiceName = "LijosWindowsService";

            Installers.Add(myProcess);
            Installers.Add(myService);

Answer 1

Your configuration and code look fine - are you sure that there is a file (yourapplication) .exe.config in the same directory as (yourapplication) .exe, the one you are running as your service?
