AutoSuggestBox异步搜索

Question

无论如何都要在TextChanged方法中进行等待搜索

private void AutoSuggestBox_TextChanged(AutoSuggestBox sender, AutoSuggestBoxTextChangedEventArgs args)
    {
        if (args.Reason == AutoSuggestionBoxTextChangeReason.UserInput)
        {
            Async Search ????!!!! 
            sender.ItemsSource = dataset;
        }
    }

例如在ContactStore中搜索以显示匹配的电子邮件，姓名，......

如果要编写await语句，则需要使方法像

一样异步

    private async Task AutoSuggestBox_TextChanged()
    {
         await task1();
    }
