问题 I'm building a Windows 10 UWP app, and would like to know if it will run on Windows Phone 8.1 and/or Windows 8.1 Desktop.

This doesn't appear to happen with primary commands (outside the menu), only secondary commands inside the overflow menu. Also, the menu item still works fine when clicked. XAML: <CommandBar> <CommandBar.SecondaryCommands> <AppBarButton Label="Test" Click="AppBarButton_Click">

问题 So when I start my UWP application I briefly get a splash screen and then an exception is thrown at: mscorlib.ni.dll!System.RuntimeTypeHandle.GetTypeByName(string name, bool throwOnError, bool ignoreCase, bool reflectionOnly, ref System.Threading.StackCrawlMark stackMark, System.IntPtr pPrivHostBinder, bool loadTypeFromPartialName) mscorlib.ni.dll!System.RuntimeType.GetType(string typeName, bool throwOnError, bool ignoreCase, bool reflectionOnly, ref System.Threading.StackCrawlMark stackMark)

问题 Basically, I am having huge difficulty getting a text file to open by my UWP app. I have set the app permissions to be able to access files in 'my documents' and other options of known libraries like 'my pictures' but any attempt to open a file not located in these places is met by an 'Access Denied' error.
