Automatically navigate to a new page after a time in UWP

Question

I'm trying to transition/navigate to a new page after a time (let's say 3 seconds), but nothing worked. I've tried this.Frame.Navigate(typeof(NewPage)); and it gives me an error "Object reference not set to an instance of an object.".

I've also tried

Thread.Sleep(3000); 
NewPage pg2 = new NewPage();
Window.Current.Content = pg2;

but it navigates immediately without waiting the 3 seconds.

The same problem I have also in am Xamarin app.

Thank you for your responses. In the mean time I've soled my problem and the code I'm using is the following:

await Task.Delay(3000);

Frame navigationFrame = Window.Current.Content as Frame;
navigationFrame.Navigate(typeof(PageToNavigateTo));
