Question/Suggestions on using a Windows Service or Hangfire

I plan on either doing a Windows Service, or using Hangfire (right in my web api), for continuously gathering new security event logs similar to that of the Windows Event Viewer.

Looking for feedback/suggestions on doing it with an event listener.

What would happen if I ran a continuous while loop for the life of the service using the following:

using EventLogWatcher logWatcher = new EventLogWatcher(query);

logWatcher.EventRecordWritten += new EventHandler<EventRecordWrittenEventArgs>((sender, e) => LogWatcher_EventRecordWritten(sender, e, domain));

try 
{	
	while (!token.IsCancellationRequested)
	{
		logWatcher.Enabled = true;
	}
}
...

Would this potentially, ever, lead to a memory leak if it runs constantly, for the life of the service running?

Any recommendations on how this should really be handled, please let me know.

Thanks

    No, but the code

        while (!token.IsCancellationRequested)
	{
		logWatcher.Enabled = true;
	}

    Is compute bound and will 100% of the cpu. Also there is no need to keep resetting the enabled. And where is the disable code? Try:

        logWatcher.Enabled = true;
    while (!token.IsCancellationRequested)
	{
        Thread.Sleep(500);
	}
    logWatcher.Enabled = false;
