I have tried some examples from Microsoft (windows universal samples).
And there is a FilePicker example.
It compiles fine but when I run it, it displays Main XAML page, but click on button, should display
FileOpenPicker and this doesn't work. It returns immediately with user canceled and nothing is displayed.
The class is Windows.Storage.Pickers.FileOpenPicker.
Is this supported on RPi, what should I use to bring FileOpen to show some file chooser.
