Displays the notification window for the specified number of milliseconds before it times out.
Assembly: System.Windows (in System.Windows.dll)
A different notification window instance is still visible.
The durationInMilliseconds period is the period that starts when the notification first fades in, and ends when the fade out animation is completed. The duration of the fade-in and fade-out is system determined. So long as the durationInMilliseconds value is greater than 2000, fade-in and fade-out times are each 1000 milliseconds.
durationInMilliseconds has an upper bound of 30000 and cannot be negative. Setting a value greater than 30000, or less than zero, throws an exception.
Calling on the same notification instance where Visibility is still true has no effect, and does not adjust the duration of display specified in the first call.
Calling on a notification instance while a different notification instance that is initiated by the application is still visible throws an exception
