Debug Windows Service

Scenario

I've got a windows service written in C#. I've read all the google threads on how to debug it, but I still can't get it to work. I've run "PathTo.NetFramework\InstallUtil.exe C:\MyService.exe". It said the install was successful, however when I run "Services.msc", The service isn't displayed at all, anywhere. If I go into Task Manager, there is a process called "MyService.vshost.exe". Pretty sure that's not it, because it's a service, not a process.

Can Someone Explain To Me?

If I am supposed to see the service when I run Services.msc? (Bearing in mind this is all being done on a local machine, with no servers AT ALL.

Other

I'm running VS2008.

EDIT:

This is all being done on my local machine, I have no servers or access to any. Also, I don't even know what the service does, I want to debug it so I can walkthrough the code and see how it all works (the code inside the service, not the service itself - for any of you smarty pants that might suggest I look at a template).

EDIT 2:

NONE OF THESE ARE WORKING! Everytime I try something I get some message about having to use NET START or install the service.

EDIT 3:

I'm running VS2008.

I typed this: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe C:\dev\Restarter\bin\Release\Restarter.exe

I got this: Microsoft (R) .NET Framework Installation utility Version 2.0.50727.3053 Copyright (c) Microsoft Corporation. All rights reserved.

Running a transacted installation.

Beginning the Install phase of the installation. See the contents of the log file for the C:\dev\Restarter\bin\ Release\Restarter.exe assembly's progress. The file is located at C:\dev\Restarter\bin\Release\EDT.Restar ter.InstallLog. Installing assembly 'C:\dev\Restarter\bin\Release\Restarter.exe'. Affected parameters are: logtoconsole = assemblypath = C:\dev\Restarter\bin\Release\Restarter.exe logfile = C:\dev\Restarter\bin\Release\Restarter.InstallLog

The Install phase completed successfully, and the Commit phase is beginning. See the contents of the log file for the C:\dev\Restarter\bin\ Release\Restarter.exe assembly's progress. The file is located at C:\dev\Restarter\bin\Release\Restar ter.InstallLog. Committing assembly 'C:\dev\Restarter\bin\Release\Restarter.exe'. Affected parameters are: logtoconsole = assemblypath = C:\dev\Restarter\bin\Release\Restarter.exe logfile = C:\dev\Restarter\bin\Release\Restarter.InstallLog

The Commit phase completed successfully.

The transacted install has completed.

C:\Program Files\Microsoft Visual Studio 9.0\VC>

I then went to RUN -> Services.msc I can see nothing in there.

There is a process in Task Manager called "Restarter.vshost.exe".

That's it.

I only wanted to install and debug it. I know it works (as it it runs and doesn't crash). But the code was written by a friend and I want to understand the underlying code by walking through it in debug mode.

How do you debug or test your Windows service without installing it?

To debug without installing, add the code as follow, mainly #if (! DEBUG). You will be able to step through the code when you run the Windows Service without installing.

What is window debug?

WinDbg is a multipurpose debugger for the Microsoft Windows computer operating system, distributed by Microsoft. Debugging is the process of finding and resolving errors in a system; in computing it also includes exploring the internal operation of software as a help to development.

I recommend following pattern for debug:

 var ServiceToRun = new SomeService();   if (Environment.UserInteractive)  {     // This used to run the service as a console (development phase only)      ServiceToRun.Start();      Console.WriteLine("Press Enter to terminate ...");     Console.ReadLine();      ServiceToRun.DoStop();  }  else  {     ServiceBase.Run(ServiceToRun);  } 

Edit: make sure that your target is Console Application, not Windows Application, otherwise it will not work.
