c# – Creating a Time Window (Notification Window)

Question:

It is necessary to create a window that opens, displays for a couple of seconds and closes itself.
In fact, this window will act as a notification.
An event occurred – a notification popped up, displayed for a couple of seconds and disappeared.
The text in the notification is different every time.
I will pass as a constructor argument, or through the DataContext.

AlarmWindow alarm = new AlarmWindow(alarmMessage);
alarm.Show();
//либо
AlarmWindow alarm = new AlarmWindow()
{
    DataContext = alarmMessage
};
alarm.Show();

Answer:

Should work like this:

void TickHandler(...)
{
    Application.Current.Dispatcher.InvokeAsync(async () =>
        {
            AlarmWindow alarm = new AlarmWindow(alarmMessage);
            alarm.Show();
            await Task.Delay(2000);
            alarm.Close();
        });
}
