How can I get the URI of the previous page in WP7?
The problem is the target platform I am using (WP 7.1) doesn't have this property "BackStack" in the "NavigationService" class. Now, how can I solve this problem in my current platform?
According to this page, BackStack is available on WP7.1.
In Windows Phone OS 7.1, functionality has been added to the NavigationService API for working with, and enabling the inspection of, the navigation history.
