问题
I use Visual Studio 2015 in Windows 10. I create universal app for Windows 8.1. I need to open the file Package.appxmanifest (for Windows Phone 8.1). I can only see message - "loaded", but manifest editor is not loaded. If I created app for Windows 10 - manifest file is opened. I read this topic. I try reinstall “Universal Windows App Development Tools” and install KB3073097 update, but it did not help.
