Simple example on how to spawn and wait for a new thread

Multithread.cs

var resetEvent = new ManualResetEvent(false);
ThreadPool.QueueUserWorkItem(
    arg =>
    {
        var task = new MyTaskRunner();
        task.Run(data);
        resetEvent.Set();

    });

/*
The code below specifies a 1 minute timeout period.
If the resetEvent WaitOne method is true, that will indicate the task completed successfully
If the resetEvent WaitOne method is fales, that will indicate the task failed to complete (i.e. it timed-out)
*/
if(!resetEvent.WaitOne(new TimeSpan(0, 0, 1, 0))){
  Console.WriteLine("The task timedout");
}

TaskRunner.cs

public class TaskRunner
    {
        public void Run(Dictionary<string, object> data)
        {
            try {
                //Do whatever
            }
            catch (System.Exception ex) {
               //Do whatever
            }
        }
    }
