I have written this system service but when I start this service, it show me error “Windows could not start the cloud_sync service on local computer. Error: 1053 the service did not respond to start and control request in timely fashion. “
and after pressing ok its status become “starting”. Please tell what is the problem with this.
I am greenhorn in c#, this is my first system service.
please help me out of this

Answer 1

You are receiving Windows could not start the cloud_sync service on local computer. Error: 1053 the service did not respond to start and control request in timely fashion because your OnStart() is not returning. You need to spin off another thread to execute your desired code.

private Task _serviceTask;
private bool _stop;

protected override void OnStart(string[] args)
{
    _serviceTask = Task.Factory.StartNew(SomeTask) 
}

// Rename the method from SomeTask to something that makes more sense
private static void SomeTask()
{
    // Move your code here
}

You should replace your while(true) to while(!_stop) so that you can gracefully end the loop within OnStop().
