I was thinking to have a shared application bar in all pages. Of course I can avoid this problem having a main page with the application bar and pages linked to the application bar without the application bar. That could be an acceptable solution.
I'm trying to figure out how I can alter the navigation history or having a page that acts as a singleton.
I have a common application bar for every page in the app. The application bar links pages A,B,C,D.
If the user tap on sequence A, B, A, B, C due the navigation service method navigate, there will be created 5 instances of pages: 2 for A, 2 for B and 1 for C and those will be stacked on navigation history.
That forse the user to navigate back 5 pages to exit the application.
How is it possible to avoid that?
Is it possible to change the state of the history? As I saw in Silverlight with method
How can be possible to have one instance Page that acts as singleton? That seems not possible to me because is not possible to navigate to an Object but just to an url.
Thank you for your support
