C# – Debug Windows Service

cdebuggingwindows-services

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

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.

Best Answer

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.
