How can I make CommonOpenFileDialog select folders only, but still show files?

Question

I am using Microsoft's CommonOpenFileDialog to allow users to select a Folder, but no files are visible when the dialog comes up. Is it possible to show files as well as folders when IsFolderPicker is set to true?

My current code looks like this

var dialog = new CommonOpenFileDialog();
dialog.IsFolderPicker = true;

if (dialog.ShowDialog() == CommonFileDialogResult.Ok)
{
    SelectedFolderPath = dialog.FileName;
}

Off the top of my head, this is how I did it

  var dialog = new CommonOpenFileDialog
  {
    EnsurePathExists = true,
    EnsureFileExists = false,
    AllowNonFileSystemItems = false,
    DefaultFileName = "Select Folder",
    Title = "Select The Folder To Process"
  };


  dialog.SetOpenButtonText("Select Folder");

  if (dialog.ShowDialog() == CommonFileDialogResult.Ok)
  dirToProcess = Directory.Exists(dialog.FileName) ? dialog.FileName : Path.GetDirectoryName(dialog.FileName);

EDIT: Holy 2 years ago Batman!

Seems like few changes were made, snippet below seems to do the job

var openFolder = new CommonOpenFileDialog();
openFolder.AllowNonFileSystemItems = true;
openFolder.Multiselect = true;
openFolder.IsFolderPicker = true;
openFolder.Title = "Select folders with jpg files";

if (openFolder.ShowDialog() != CommonFileDialogResult.Ok)
{
    MessageBox.Show("No Folder selected");
    return;
}

// get all the directories in selected dirctory
var dirs = openFolder.FileNames.ToArray();
