从 Silverlight 异步调用返回的对象会丢失其包含的聚合

Question

从 Silverlight 2.0 控件到 WebService 的调用（通过 MyWebServiceNameEventArgs 返回）不会返回包含的 List<> 。 聚合体。 例如，我有一个包含 List 和 List 的 Person 类。 当我跟踪呼叫时，我发现此人的列表已正确填充。 但是，当它通过 MyWebServiceNameEventArgs 到达时，列表为空。 正确返回诸如 FirstName、DOB 等简单类型。

我需要做什么才能返回所附的聚合吗？

这是我的代码：

private void btnGetPerson_Click(object sender, RoutedEventArgs e)
{
  var proxy = new TutorWCFServicesClient();
  proxy.GetPersonWithPersonKeyOfCompleted += new EventHandler<GetPersonWithPersonKeyOfCompletedEventArgs>(proxy_GetPersonWithPersonKeyOfCompleted);
  var perID = 29; // testing
  proxy.GetPersonWithPersonKeyOfAsync(perID);
}

void proxy_GetPersonWithPersonKeyOfCompleted(object sender, GetPersonWithPersonKeyOfCompletedEventArgs e)
{
  var per = e.Result;
  if (per != null)
  {
    FirstName.Text = per.FirstName;
    LastName.Text = per.LastName;
    if (per.Phones != null)
    {
      var hPhone = (from phone in per.Phones where phone.PhoneType.ToLower() == "home" select phone).FirstOrDefault();
      var cPhone = (from phone in per.Phones where phone.PhoneType.ToLower() == "cell" select phone).FirstOrDefault();
      var wPhone = (from phone in per.Phones where phone.PhoneType.ToLower() == "work" select phone).FirstOrDefault();

      if (hPhone != null)
      {
        PhoneHome.Text = string.Format("({0}) {1}-{2}", hPhone.AreaCode, hPhone.Exchange, hPhone.Number);
      }
      if (cPhone != null)
      {
        PhoneCell.Text = string.Format("({0}) {1}-{2}", cPhone.AreaCode, cPhone.Exchange, cPhone.Number);
      }
      if (wPhone != null)
      {
        PhoneSchool.Text = string.Format("({0}) {1}-{2}", wPhone.AreaCode, wPhone.Exchange, wPhone.Number);
      }
    }
  }
  else
  {
    FirstName.Text = "Not Found";
  }
}

愚蠢的错误，我忘记刷新 Silverlight 应用程序中的 ServiceReference。
