Debugging A Window System Service in C#

I get the error "Cannot start service from the command line or a debugger. A Windows Service must first be installed (using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool or the NET START command.

So, is there not a way to run or test the Windows Service without installing it? Should I build my project in a Console Application, then transfer the code to a Windows Server project after it has been tested?

Thanks.

there are two approaches you can use.

  1. Create separate windows form application and call that code from the windows form project.

  2. in the calling method, please use:

     #if Debug
 Debugger.Launch()
 #endif

I hope it helps.

I tend to add a static Main method to my service class so that it can be invoked as a console application for debugging, but installed and ran as a service as well.

Something similar to the following:

    public partial class ControllerService : ServiceBase
    {

        static void Main(string[] args)
        {
            ControllerService service = new ControllerService();

            cmdLine = CommandLineParser.Parse(args);

            if (Environment.UserInteractive)
            {
                switch (cmdLine.StartMode)
                {
                    case StartMode.Install:
                        //Service Install Code Here
                        break;
                    case StartMode.Uninstall:
                        //Service Uninstall Code Here
                        break;
                    case StartMode.Console:
                    default:
                        service.OnStart(args);
                        consoleCloseEvent.WaitOne();
                        break;
                }
            }
            else
            {
                ServiceBase.Run(service);
            }
        }

        protected override void OnStart(string[] args)
        {
             //Do Start Stuff Here
        }

        protected override void OnStop()
        {
            if (Environment.UserInteractive)
            {
                consoleCloseEvent.Set();
            }
        }
   }

You could try to keep the code that performs the actual work in a separate assembly, and call that code from the service or a console application for testing.
