Notification and Action Center Windows Phone 8.1

Question

Hey,

 

 I am porting my windows Phone 8 app to Windows Phone 8.1, which contain the Reminder part, When Reminder plays it shows the reminder Alert box, What I want is, I want to show Notification too at same time, and the Notification details will show in Action Center, Can you tell me code?

My Reminder Code is
var newReminder = new Reminder(_Date.ToString())
{
Content = _Content,
BeginTime = _Date,
RecurrenceType = RecurrenceInterval.None,
NavigationUri = navigationUri,
// sound= new Uri("music1.wav",UriKind.Relative)
};
ScheduledActionService.Add(newReminder);

Now at Reminder time, want to show Notification and add the content in Action Center, So please tell me code.
