OpenFilePicker example code hangs, never produces picker

[EvanHutnick]

When attempting to run the code from 'Pick a single file: complete code listing' via Visual Studio, the application simply hangs and never generates a file picker.

Tested on Debug/Release, x86/x64, Admin/non admin opening of Visual Studio. Also gave file picker 'any file type' permission just in case. Currently on SDK 16299, OS Version 1709 build 17025.1000.

I tested this code, and it worked for me. I'm on an Insider Preview build (17655). No special permissions or admin privileges. The code is the same as what's on the page, except I added "Debug.WriteLine" instead of a text box and wrapped it into a method.

public async void TestPicker() 
{
    var folderPicker = new Windows.Storage.Pickers.FolderPicker();
    folderPicker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.Desktop;
    folderPicker.FileTypeFilter.Add("*");

    Windows.Storage.StorageFolder folder = await folderPicker.PickSingleFolderAsync();
    if (folder != null)
    {
        // Application now has read/write access to all contents in the picked folder
        // (including other sub-folder contents)
        Windows.Storage.AccessCache.StorageApplicationPermissions.
        FutureAccessList.AddOrReplace("PickedFolderToken", folder);
        Debug.WriteLine(folder.Name);
    }
    else
    {
        Debug.WriteLine("Operation canceled.");
    }
}

If you're still having issues with the file picker, I'll file a bug with the product team to investigate. Thanks for bringing this up!
