targeting WP 8.0 app to WP8.1 app?

问题

I installed Visual Studio 2013 (With Update 2)

and i was working on my Project in VS2012 for Windows Phone 8.0

And now i decided to Upgrade it to a Windows Phone 8.1 app

so i followed the instructions and Targeted the app !

and everything's done successfully , BUT! the app now is (Windows Phone Silverlight 8.1)

Picture:

unlike other people who targeted to (Windows Phone 8.1) , there is a huge difference between the two types of the projects

I can't use the new XAML controls - Windows.UI.XAML

What can i do to fix this?

回答1:

Silverlight XAML and the new Win8.1/WinPhone8.1 XAML (aka XAML for WinRT) are two different things.
If you started your app with Silverlight you have to stick to it, or create your whole UI again with the new XAML (which as I said, it is now compatible with Win8.1)
