Error after stopping service through Task Scheduler

I've a running service on Windows Server 2012 called FileWatcher. It checks files into folders and does other stuff. I have to stop and restart the service every day at 2.00 AM so i configured two scheduled tasks: the first one stops the service at 2.00 AM, the second one starts it at 2.01 AM.

Everything is working. The service stops, then it restarts. But if I check the Event Viewer I find some errors.

2.00.00 AM : Service stopped successfully.
2.00.00 AM : Failed to stop service. System.InvalidOperationException: An unhandled exception was detected ---> System.InvalidOperationException: Cannot read keys when either application does not have a console or when console input has been redirected from a file. Try Console.Read.
2.00.00 AM : Description: The process was terminated due to an unhandled exception. Exception Info: System.InvalidOperationException
2.00.00 AM : Faulting application name: FileWatcher.exe, version: 1.0.0.0, time stamp: 0x5aeae776 Faulting module name: KERNELBASE.dll, version: 6.3.9600.18340, time stamp: 0x5736541b Exception code: 0xe0434352 Fault offset: 0x00014878 Faulting process id: 0x1a6c
2.01.01 AM Service Started Successfully.

What's going on? I mean, the service stops and restarts, why I get these errors? I already checked in another similar question, and the guy solved changing the project from Windows Application to Console Application. Mine was already Console App.

Thank you in advance, M.

Solution

Can you repeat the error when you run / stop service by hand? Can you find the line, where this happens?

Cannot read keys when either application does not have a console or when console input has been redirected from a file. Try Console.Read.

This is a wild guess, but you have Console.ReadKey() somewhere in your service.
