How to host service as a Windows Services

We can host services three ways…

1. Self Host

2. IIS

3. Window Service

 

This article is for Hosing service as a Windows Services.

I have following services..

Code Snippet

1. using System;
2. using System.Collections.Generic;
3. using System.Linq;
4. using System.Text;
5. using System.ServiceModel;
7. namespace CalcService
8. {
9.    [ServiceContract]
10.     public interface ICalc
11.     {
12.        [OperationContract]
13.        int GetSum(int i, int j);
14.     }
17.    public class CalcServices : ICalc
18.    {
20.        #region ICalc Members
22.        public int GetSum(int i, int j)
23.        {
24.            return i + j;
25.        }
27.        #endregion
28.    }
29. }

 

Following is the App.config.

 

Code Snippet

1. <?xml version=“1.0“ encoding=“utf-8“ ?>
2. <configuration>
3.   <system.serviceModel>
5.     <services>
7.       <service name=“CalcService.CalcServices“>
8.         <endpoint address=“” binding=“basicHttpBinding“ contract=“CalcService.ICalc“/>
9.         <host>
10.           <baseAddresses>
11.             <add baseAddress=“http://localhost:1234/CalcServices“/>
12.           </baseAddresses>
13.         </host>
14.         
15.         
16.       </service>
17.       
18.     </services>
19.     
20.     
21.     
22.   </system.serviceModel>  
25. </configuration>

Now Add two files in the solution.

1. Windows Service and

2. Installer Class

Write down following code into Service1 (Windows Service class) class..

Code Snippet

1. using System;
2. using System.Collections.Generic;
3. using System.ComponentModel;
4. using System.Data;
5. using System.Diagnostics;
6. using System.Linq;
7. using System.ServiceProcess;
8. using System.Text;
9. using System.ServiceModel;
11. namespace CalcService
12. {
13.     partial class Service1 : ServiceBase
14.     {
15.         public Service1()
16.         {
17.             InitializeComponent();
18.         }
19.         ServiceHost sn;
20.         protected override void OnStart(string[] args)
21.         {
22.             sn = new ServiceHost(typeof(CalcService.CalcServices), new Uri[] { });
23.             sn.Open();
24.         }
26.         protected override void OnStop()
27.         {
28.             sn.Close();
29.         }
30.     }
31. }

Write down following code into Installer1

Code Snippet

1. using System;
2. using System.Collections;
3. using System.Collections.Generic;
4. using System.ComponentModel;
5. using System.Configuration.Install;
6. using System.Linq;
7. using System.ServiceProcess;
10. namespace CalcService
11. {
12.     [RunInstaller(true)]
13.     public partial class Installer1 : Installer
14.     {
15.         public Installer1()
16.         {
17.             InitializeComponent();
20.             ServiceProcessInstaller processInstaller = new ServiceProcessInstaller();
21.             ServiceInstaller serviceInstaller = new ServiceInstaller();
23.             processInstaller.Account = ServiceAccount.LocalSystem;
25.             serviceInstaller.DisplayName = “Service1″;
26.             serviceInstaller.Description = “CalcService.”;
27.             serviceInstaller.ServiceName = “Service1″;
28.             serviceInstaller.StartType = ServiceStartMode.Manual;
30.             Installers.Add(processInstaller);
31.             Installers.Add(serviceInstaller);
33.         }
34.     }
35. }

Now we have written both the service and Installer. Now we have to write code for start up means some ware I’ve to call ..

I’ve written in main program

 

Code Snippet

1. using System;
2. using System.Collections.Generic;
3. using System.Linq;
4. using System.Text;
5. using System.ServiceProcess;
7. namespace CalcService
8. {
9.     class Program
10.     {
11.         static void Main(string[] args)
12.         {
13.             ServiceBase[] ServicesToRun;
15.             ServicesToRun = new ServiceBase[] { new Service1() };
17.             ServiceBase.Run(ServicesToRun);
19.         }
20.     }
21. }

 

Now we have done everything. Final step is after compiling the solution, we have to install through command prompt.

 

c:> Installutil –i c:…..DebugCaleService.exe

 

Now if you check in service.msi, you can get the service.

Hope this is useful …:)
