问题 In windows phone 8, its very easy to add an App Bar and manage it, but now i test new windows phone 8.1 SDK to build a project with new Geofencing feature but i don't know how to add an App Bar in the App. 回答1: In Windows Phone 8.1, We can use BottomAppBar to add App Bar.

问题 Is there have way to know a StorageFolder-obj belongs to SD or Phone on WP8.1? Thanks you. 回答1: You can do it for example by checking the Path of StorageFolder (or StorageFIle ): string folderPath = yourStorageFolder.Path; if (folderPath.StartsWith("C:")) // on Phone else // on SD Card if it begins with D: (or other letter - not C: ) - it means it belongs to SD card, if it begins with C: - it exists on Phone, EDIT - as Adam has said in comments - it may be more suitable to check first if file

问题 I created a universal app via Microsoft's AppStudio. I tried adding Facebook authentication to the app by following the 'Scrumptious tutorial' (http://facebooksdk.net/docs/phone/tutorial/). When I run the app on my phone, I can never get to the facebook login page, because the following line: await App.FacebookSessionClient.LoginAsync("user_about_me,read_stream"); always results in the following exception: System.NotImplementedException: Not implemented at Windows.Security.Authentication.Web

问题 How to hide the Status bar in Windows Phone 8.1 (C#, XAML)? In Windows Phone 8 it was done by setting shell:SystemTray.IsVisible="False" at any page. But its not available in Windows Phone 8.1 回答1: With the release of Windows Phone 8.1 SDK comes a new StatusBar. The StatusBar replaces the SystemTray from Windows Phone Silverlight Apps.
