C# Class Candor.Tasks.ServiceProcess.ServiceMonitorWorkerRoleTask

Monitors that a service is up either directly or by checking for updates to a file that it generates. When a monitored service stops working, attempts are made to restart the service or the server it runs on.

The service being monitored can be on any machine in the same domain. If not on a domain, then only the current machine can be monitored and restarted.
