public class WorkerRole : RoleEntryPoint
{
    public override bool OnStart()
    {
        RoleEnvironment.StatusCheck += RoleEnvironmentStatusCheck;
        return base.OnStart();
    }

    // Use the busy object to indicate that the status of the role instance must be Busy
    private volatile bool busy = true;

    private void RoleEnvironmentStatusCheck(object sender, RoleInstanceStatusCheckEventArgs e)
    {
        if (this.busy)
        {
            // Sets the status of the role instance to Busy for a short interval.
            // If you want the role instance to remain busy, add code to
            // continue to call the SetBusy method
            e.SetBusy();
        }
    }

    public override void Run()
    {
        Trace.TraceInformation("Worker entry point called", "Information");

        while (true)
        {
            Thread.Sleep(10000);
        }
    }

    public override void OnStop()
    {
        base.OnStop();
