问题 As stated in the question below, Setters cannot contain Bindings in Windows RT/Phone 8.1 => Binding SelectedItems in ListView to a ViewModel in Windows Phone 8.1 Has this changed in the new Universal Windows Applications? Still not Bindings in values? 回答1: OK, you can't bind to the DataContext using the normal ways, but you can do it using other (smart) methods: Please, look at this.

问题 How can I register my windows phone 8.1 runtime app so that it appears in the poto edit list? The only way I see is to create an app for windows phone 8.0 silverlight (there is a template in VS 2013) then edit the wmappmanifest.xml and then upgrade the project to wp81. But I think there must be another way to achieve that directly in a wp81 runtime project. Does anyone know how to do that properly? 回答1: According to MSDN article Migrating your Windows Phone 8 app to a Windows Runtime XAML app

问题 Hey I was wondering if it was possible to spin up Bing vision from within my application and get the returned picture. I know I can spin up the camera, but is it possible to spin it up with the bing lense? 回答1: You can open lenses only as this Windows Phone app (that opens Bing Vision).
