When you attempt to start the service, you receive the following error message: Could not start the
PollingService service on the local computer. Error 1053: The service did not respond to the start or
control request in a timely fashion.
You need to modify the service application code so that the service starts properly.
What should you do?
A. Move the loop code into the constructor of the service class from the OnStart method.
B. Drag a timer component onto the design surface of the service. Move the calls to the long-running
procedure from the OnStart method into the Tick event procedure of the timer, set the Enabled property of
the timer to True, and call the Start method of the timer in the OnStart method.
C. Add a class-level System.Timers.Timer variable to the service class code. Move the call to the DoWork
method into the Elapsed event procedure of the timer, set the Enabled property of the timer to True, and
