Enumerate JumpList recent files?

Question

I'm populating a jumplist via:

    public static void AddToList(String path)
    {
        var jumpList = JumpList.GetJumpList(Application.Current);
        if (jumpList == null) return;

        string title = System.IO.Path.GetFileName(path);
        string programLocation = Assembly.GetCallingAssembly().Location;

        var jt = new JumpTask
        {
            ApplicationPath = programLocation,
            Arguments = path,
            Description = path,
            IconResourcePath = programLocation,
            Title = title
        };

        JumpList.AddToRecentCategory(jt);

        jumpList.Apply();
    }

Which works great. The only problem is that I also have a file menu in my application and would like to show the recent list there as well. I could do it easily by storing a second copy of the recent files, but I was wondering if I could possibly enumerate the list of files used by the jumplist. I haven't been able to figure out anything for doing so.

Am I missing something here? Can I enumerate the files in the jumplist, or do I need to store my own duplicate list?

I have checked your code. And I have the question to it. I looked into MSDN page that you provided. And there I see example of adding task:

private void AddTask(object sender, RoutedEventArgs e)
{
  //....
  //Mostly the same code as your
  JumpList jumpList1 = JumpList.GetJumpList(App.Current);
  jumpList1.JumpItems.Add(jumpTask1); // It is absent in your code!!!
  JumpList.AddToRecentCategory(jumpTask1);
  jumpList1.Apply();
}

I have created two my own methods Create and Extract and I can access to created during current session task at least. This is my code:

private void Extract()
{
    var jumpList = JumpList.GetJumpList(Application.Current);

    if (jumpList == null) return;

    foreach (var item in jumpList.JumpItems)
    {
        if(item is JumpTask)
        {
            var jumpTask = (JumpTask)item;
            Debug.WriteLine(jumpTask.Title);
        }
    }
}
private void Create() {
    var jumpList = JumpList.GetJumpList(Application.Current);

    if (jumpList == null)
    {
        jumpList = new JumpList();
        JumpList.SetJumpList(Application.Current, jumpList);
    }

    string title = "Title";
    string programLocation = "Location";
    var path = "path";

    var jt = new JumpTask
    {
        ApplicationPath = programLocation,
        Arguments = path,
        Description = path,
        IconResourcePath = programLocation,
        Title = title
    };
    jumpList.JumpItems.Add(jt);
    JumpList.AddToRecentCategory(jt);
    jumpList.Apply();
}

I am not sure that this is answer on your question, but I am looking to reason why you don't add your task to JumpItems list?
