Question

I have a WCF app that accepts requests to start a job. Each job needs to do something after exactly X minutes (e.g. 5 mins.), there can also be a job request at any time and simultaneously.

This is what I have in mind,

// WCF class  
public class RequestManager  
{
   // WCF method
   public void StartNewJob()
   {
      // start a new thread with timer for each job?
   }
}

public class Job
{
   public Job()
   {
      // do some initializations

      // do something after x mins

      // sleep or timer?
   }

   private void DoSomething()
   {
      // do some follow-ups
   }
}

With my approach, I’m afraid that there will be too many threads that’s doing nothing for X mins. Per-second accuracy would be a requirement as well (say it starts a job at 0:05:01, the follow up should be at 0:10:01).

What would be the best way to approach this?

You need to use some timing/scheduling framework like Quartz.NET or create your own one (lightweight).
