Проблемы с планировщиком заданий в Windows с .NET

Question

Я использую Task Scheduler Managed Wrapper от https://taskscheduler.codeplex.com/, чтобы создать приложение для таргетинга .NET 4 на Windows 7, которое создает несколько задач после удаления старых, которые оно создало.

регистрация Задачи кажется, чтобы добиться успеха, но задачи не запускаются и какой-то образом повреждены Task Scheduler следующим образом:

диалоговое окно ошибки в изображении появляется шесть раз, что то, как много задач, мои приложение удалено, а затем воссоздано. Это происходит при первом запуске Task Scheduler MMC Console, а также при выборе папки House of Synergy.

код немного длительный, но необходимый и готов к компиляции:

namespace TaskSchedulerHelper 
{ 
    using System; 
    using System.Diagnostics; 
    using System.Linq; 
    using System.Security.Principal; 
    using System.Windows.Forms; 
    using Microsoft.Win32.TaskScheduler; 

    internal static class Program 
    { 
     [STAThread] 
     private static void Main (string [] args) 
     { 
      var now = DateTime.Now; 
      var folderName = @"House of Synergy"; 
      var taskNamePrefix = @"ShutDown Power Outage"; 
      var applicationName = @"Task Scheduler Helper"; 

      var times = new TimeSpan [] 
      { 
       TimeSpan.FromHours(02), // 02:00 AM 
       TimeSpan.FromHours(06), // 06:00 AM 
       TimeSpan.FromHours(11), // 11:00 AM 
       TimeSpan.FromHours(15), // 03:00 PM 
       TimeSpan.FromHours(19), // 07:00 PM 
       TimeSpan.FromHours(23), // 11:00 PM 
      }; 

      try 
      { 
       Console.Title = applicationName; 

       Console.WriteLine(applicationName); 
       Console.WriteLine();

        var tasks = folder

Комментирование task.RegisterChanges(); и две последующие строки, кажется, чтобы исправить эту проблему.
