Question

I have wrote a Windows Service and I have a admin panel which I can configure this service from a web page. In order to this I am using a database. So basically what I am doing is I change the values from the db and the service reads it and it changes its execution time.. etc.

My problem is in my development server everything works fine. When I install my service and upload the web page to the production server I am getting this error

The type or namespace name ‘ServiceController’ could not be found (are you missing a using directive or an assembly reference?)

It is giving this error in my web page. I have checked the service it is installed and works fine but when I am trying to go to the configuration page for the service it hrows this exception. In my project i see that I have using System.ServiceProcess; is added in the top and when I build my solution this dll reference error doesnt show up. Also in the designer it seems like it is already imported:

<@ Import Namespace="System.ServiceProcess">; What might be the problem? Can it be a 32-bit / 64-bit issue? ( I know it doesnt make sense but any help will be appreciated)

ServiceController agService = new ServiceController("Buddy Service");
while (agService.Status == ServiceControllerStatus.Running)
{                   
  lblServiceStatus.Text = "Running";
  lblServiceStatus.ForeColor = Color.LimeGreen;
  btnStopService.Enabled = true;
  btnStartService.Enabled = false;
  break;
}

It throws the exception on the line

ServiceController agService = new ServiceController("Buddy Service");

I have made sure that “Buddy Service” is in the Services list and it does.

It sounds like you have the assembly referenced correctly.

Try changing this line:

ServiceController agService = new ServiceController("Buddy Service");

to this:

var agService = new System.ServiceProcess.ServiceController("Buddy Service");

If this works, you will probably also need to change this line:

while (agService.Status == ServiceControllerStatus.Running)

to this:

while (agService.Status == System.ServiceProcess.ServiceControllerStatus.Running)
