How to dowload/upload file onto a users onedrive

Question

I am in a Highschool club where we create windows store apps. I am in charge of the code that allows the user to either download files from their online onedrive storage, or upload files. So far I have successfully logged the user in and gained access to onedrive and display the users name with the following code:

 private async void LoadProfile()
        {
            bool connected = false;
            string text = "No Error:";

            try
            {
                var authClient = new LiveAuthClient();
                LiveLoginResult result = await authClient.LoginAsync(new List<string>() {"wl.signin", "wl.skydrive"});


                if (result.Status == LiveConnectSessionStatus.Connected)
                {
                    connected = true;
                    var connectClient = new LiveConnectClient(result.Session);
                    var meResult = await connectClient.GetAsync("me");
                    dynamic meData = meResult.Result;
                    Textblock_profilename.Text = meData.name;
                }
            }
            catch (LiveAuthException ex)
            {
                //Set text to corresponding error
                text = ex.ToString();
            }
            catch (LiveConnectException ex)
            {
                //Set text to corresponding error 
                text = ex.ToString();
            }


            if (text[0].ToString() != "N")
            {
                var dialog = new Windows.UI.Popups.MessageDialog(text);
                await dialog.ShowAsync();
            }

        }

I gained the code from the following MSDN tutorial: http://msdn.microsoft.com/en-us/library/dn631823.aspx

However when I try to follow the next step, downloading and uploading files, I cannot get it to work. Right now I am just trying to press a button, and have the code download a test file:

  private async void Button_downloadFile_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                LiveDownloadOperation operation = await connectClient.CreateBackgroundDownloadAsync("skydrive/documents/enter_path");
                var result = await operation.StartAsync();
                //DO SOMETHING WITH RESULT HERE

            }
            catch
            {
                // Handle any errors.
            }
        }

However this code throws the following errors:

This is straight from the MSDN tutorial, and can't figure out how to fix the error. My best guess is I'm missing a "using" statement, but can't figure out what I am missing. Thanks for any and all help!

Make sure you're updated to use the Live SDK 5.6 binary. Be sure to let us know if you have any other problems with OneDrive integration!
