System.Windows.Forms.Timer is not Working in my WCF service

I have created a restful WCF service.Whenever client is calling this service method i have started a Timer with certain interval like below

var timer = new Timer();
timer.Interval = Convert.ToInt32(attempt);
timer.Tick += new EventHandler(timer_Tick);
var tempAttempt = new TempAttempt
{
    AlertInformationId = currentAlertId,
    Attempt = GetAttemptId(attempt),
    Status = false,
    TimerId = "Timer" + currentAlertId.ToString()
};

if (CreateNewAttempt(tempAttempt))
{
    timer.Tag = tempAttempt.TimerId;
    timer.Enabled = true;
    timer.Start();
}

private void timer_Tick(object sender, EventArgs e)
{
    //blah blah          
    Timer t = (Timer)sender;
}

After starting the timer the tick is not happened after that particular interval.How can i resolve this?

My Service

[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, UriTemplate = "/PushNotification")]
[OperationContract]
void PushNotification(MailInformation mailInformations);

From this linkTimer Class

This Windows timer is designed for a single-threaded environment where UI threads are used to perform processing. It requires that the user code have a UI message pump available and always operate from the same thread, or marshal the call onto another thread.

Meaning that you cannot use System.Windows.Forms.Timer in this case, it wont work.

System.Windows.Forms.Timer is the wrong class for a service.

try System.Threading.Timer instead.
