The type or namespace name ‘ServiceController’ could not be found

Many times you need to add namespaces to your application, here I sharing how you can add “System.ServiceProcess” required to incorporate windows services to your application.

Follow the below steps add references:

1) Right click on solution explore and click on “Add reference..”

2) go to Assembly => Framework and look for “System.ServiceProcess” and enable it.

Click OK to enable it.

3) Now add below line at the top:

using System.ServiceProcess;

4) Add the code below:

ServiceController svcController = new ServiceController("Test Windows Service");
if (svcController != null)
{
    try
    {
        //svcController.Stop();
        //svcController.WaitForStatus(ServiceControllerStatus.Stopped, TimeSpan.FromSeconds(10));
        svcController.Start();
    }
    catch
    {
    }
}
