NavigationService.BackStack.FirstOrDefault() does not contains definition in Windows Phone 8?
c#, navigationservice, windows-phone-8
Solution
Don't forget to add `using System.Linq;` at the top of your code file.
Problem
I am trying to get the last page in the navigation using the following in WP8 ``` var lastPage = NavigationService.BackStack.FirstOrDefault(); ``` However Visual Studio 12 complaints that it does not contain a definition for `FirstOrDefault`
