azure mobile services - ปัญหาฝั่ง client - ทำไมเรียกข้อมูลได้แค่ 50 records ฉันไม่ต้องการ paging นะ

        private MobileServiceCollection<Country, Country> CountryItems;
        private IMobileServiceTable<Country> countryTable = App.MobileService.GetTable<Country>();

        private async void Page_Loaded(object sender, RoutedEventArgs e)
        {
            MobileServiceInvalidOperationException exception = null;
            try
            {
                CountryItems = await countryTable.OrderBy(c => c.CountryName).ToCollectionAsync();
            }
            catch (MobileServiceInvalidOperationException ex)
            {
                exception = ex;
            }

            if (exception != null)
            {
                await new MessageDialog(exception.Message, "Error loading items").ShowAsync();
            }
            else
            {
                this.ComboBoxCountry.ItemsSource = CountryItems;
                this.ComboBoxCountry.DisplayMemberPath = "CountryName";
                this.ComboBoxCountry.SelectedValuePath = "Id";
            }
        }

query = query.IncludeTotalCount(); // ไม่ได้ ออก -1 (คืออะไร ???)

// You can also use the IncludeTotalCount method to ensure that the query will get the total count for all the records
// that would have been returned, ignoring any take paging/limit clause specified:

countryTable.OrderBy(c => c.CountryName).Skip(0).Take(200).ToCollectionAsync(); // ไม่ได้ ออก 50 อันเท่าเดียว
