Hi,
In my Game I can’t open the NativeFile picker. I created a seperate Visual Studio project and followed this tutorial. The main code to open the FilePicker is:

#if NETFX_CORE
        public async void OpenFilePicker()
        {
            var picker = new Windows.Storage.Pickers.FileOpenPicker();
            picker.ViewMode = Windows.Storage.Pickers.PickerViewMode.List;
            picker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;
            picker.FileTypeFilter.Add(".png");

            var file = await picker.PickSingleFileAsync();
            if (file != null)
            {
                this.onFileSelected?.Invoke(file.Name);
            }
        }
#endif
    }

If I build the Project and try to access the FilePicker I got the following error:

4826123--462965--error.png

I hope someone could help me.

OpenFilePicker needs to be called on the UI thread. See this post for details:

what is ShowOpenPanel input?

  • public static string ShowOpenPanel(bool includeFiles, bool includeDirectories)
  • {
  • Application.InvokeOnUIThread(async () => {
  • var filePicker = new FileOpenPicker();
  • filePicker.FileTypeFilter.Add(“*”);
  • var file = await filePicker.PickSingleFileAsync();
  • }, false);
  • return string.Empty;
  • }
