How to remove page from Navigation History?

How do I remove a page from the Navigation History?

I go forward like this:

this.Frame.Navigate(typeof(...));

But what I want is

A -> B -> C -> D -> E

Back?

E -> A

So I want to delete the Backward Navigation Stack. NavigationService is not available in Windows 8 as far as I know. And I don't find any useful function in the page class:

On UWP, Frame.BackStack.Clear() works fine (since it's IList<PageStackEntry>).

Also, you may use other IList methods (such as RemoveAt) to accomplish your task.

I had same issue and I done this using the below code

while (Frame.BackStackDepth > 0)
{
    if (Frame.CanGoBack)
    {
        Frame.GoBack();
    }
}
Frame.CacheSize = 0;
Frame.Navigate(typeof(LoginScreen));

One way is to use Frame.SetNavigationState. When you're on page A, store Frame.GetNavigationState in a static variable which is accessible anywhere in the app. 

MyClass.PageANavigationState = Frame.GetNavigationState();

When you're on E (or whichever page), and you want to clear the navigation stack up to A, use

Frame.SetNavigationState[MyClass.PageANavigationState];
