copied!<p>Absolutely you can. You can even do it with <code>csc</code>. The only thing in VS is the <strong>template</strong>. But you can reference the System.ServiceProcess.dll yourself.</p> <p>Key points:</p> <ul> <li>write a class that inherits from <code>ServiceBase</code></li> <li>in your <code>Main()</code>, use <code>ServiceBase.Run(yourService)</code></li> <li>in the <code>ServiceBase.OnStart</code> override, spawn whatever new thread etc you need to do the work (<code>Main()</code> needs to exit promptly or it counts as a failed start)</li> </ul> <h2>Sample Code</h2> <p>Very basic template code would be:</p> <p><strong>Program.cs</strong>:</p> <pre><code>using System; using System.ServiceProcess; namespace Cron { static class Program { /// <summary> /// The main entry point for the application. /// </summary> static void Main() { System.ServiceProcess.ServiceBase.Run(new CronService()); } } } </code></pre> <p><strong>CronService.cs</strong>: </p> <pre><code>using System; using System.ServiceProcess; namespace Cron { public class CronService : ServiceBase { public CronService() { this.ServiceName = "Cron"; this.CanStop = true; this.CanPauseAndContinue = false; this.AutoLog = true; } protected override void OnStart(string[] args) { // TODO: add startup stuff } protected override void OnStop() { // TODO: add shutdown stuff } } } </code></pre> <p><strong>CronInstaller.cs</strong>:</p> <pre><code>using System.ComponentModel; using System.Configuration.Install; using System.ServiceProcess; [RunInstaller(true)] public class CronInstaller : Installer { private ServiceProcessInstaller processInstaller; private ServiceInstaller serviceInstaller; public CronInstaller() { processInstaller = new ServiceProcessInstaller(); serviceInstaller = new ServiceInstaller(); processInstaller.Account = ServiceAccount.LocalSystem; serviceInstaller.StartType = ServiceStartMode.Manual; serviceInstaller.ServiceName = "Cron"; //must match CronService.ServiceName Installers.Add(serviceInstaller); Installers.Add(processInstaller); } } </code></pre> <p>And a .NET service application is not installed the same way as normal service application (i.e. you can't use <code>cron.exe /install</code> or some other command line argument. Instead you must use the .NET SDK's <code>InstallUtil</code>:</p> <pre><code>InstallUtil /LogToConsole=true cron.exe </code></pre> <h2>Resources</h2> <ul> <li><a href="http://www.codeguru.com/csharp/csharp/cs_network/windowsservices/article.php/c6027/" rel="noreferrer">Creating a Windows Service in .NET</a> by Mark Strawmyer</li> <li><a href="http://blogs.msdn.com/b/bclteam/archive/2005/03/15/396428.aspx" rel="noreferrer">Writing a Useful Windows Service in .NET in Five Minutes</a> by Dave Fetterman</li> <li><a href="http://msdn.microsoft.com/en-us/library/aa984379%28v=vs.71%29.aspx" rel="noreferrer">Installing and Uninstalling Services</a></li> <li><a href="http://msdn.microsoft.com/en-us/library/aa984464%28v=vs.71%29.aspx" rel="noreferrer">Walkthrough: Creating a Windows Service Application in the Component Designer</a></li> </ul>
