Could not find property named - C#

Формулировка задачи:

Всем привет. В C# я новичок. Довелось мне работать с такой штукой как SCOM и импортировать в него паки. Беру первый пример из интернета: Main.cs

class Program
    {
        static void Main(string[] args)
        {
              StaticHelpers.ImportMp();
        }
     }

StaticHelpers.cs:

public class StaticHelpers
{
      internal static void ImportMp() 
     {
          String pack = "MyNewPack.mp";
          ManagementGroup managementGroup = new ManagementGroup("localhost");
          String currentDirecoty = Directory.GetCurrentDirectory();
          ManagementPack mp = new ManagementPack(currentDirecoty + pack);
          managementGroup.ManagementPacks.ImportManagementPack(mp);
     }
}

Получаю ошибку:

Class Initialization method Tests.ClassInitialize threw exception. Microsoft.EnterpriseManagement.Configuration.ExtensionException: Microsoft.EnterpriseManagement.Configuration.ExtensionException: Could not find property named Action on type System.Collections.Generic.ICollection`1[[Microsoft.EnterpriseManagement.Configuration.ManagementPackActionType, Microsoft.EnterpriseManagement.Core, Version=7.0.5000.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]], mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089.</Message>

Перепробовал множество вариантов коннекта к СКОМ, за коннект отвечает эта строка: ManagementGroup managementGroup = new ManagementGroup("localhost"); делал и так: ManagementGroup managementGroup = new ManagementGroup.Connect("localhost"); и так: ManagementGroupConnectionSettings mgSettings = new ManagementGroupConnectionSettings("localhost"); ManagementGroup managementGroup = new ManagementGroup(mgSettings); и кучу всего еще. Во всех случаях падает на строке с "....new ManagementGroup...." Подскажите пожалуйста, что я могу делать не так? Что вообще значит ошибка "Could not find property named"? Перевести я могу, мне бы поглубже объяснение. В классе ManagementGroup нет никаких переменных Action, так же как и в классе, от которого он наследуется(EnterpriseManagementGroup). В общем, буду рад любой подсказке, в какую сторону копать.
