Мое приложение иногда выдает исключение:

Тип исключения: InvalidOperationException Сообщение об исключении: коллекция была изменена; Операция перечисления может не выполняться.

А вот и трассировка стека

    Exception type: InvalidOperationException 
    Exception message: Collection was modified; enumeration operation may not execute.

   at System.Resources.ResourceManager.InternalGetResourceSet(CultureInfo culture, Boolean createIfNotExists, Boolean tryParents)
   at System.Resources.ResourceManager.GetString(String name, CultureInfo culture)

И вот мой код:

public IList<Function> MapWithLanguage(IList<Function> list)
{
    if (list == null)
    {
        return null;
    }
    var currentResource = Type.GetType("Fanex.Athena.Models.ViewModel.Menu, Fanex.Athena.Models");
    ResourceManager rm = new ResourceManager(currentResource);
    var newList = new List<Function>();
    foreach (var func in list)
    {
        newList.Add(new Function
        {
            Name = rm.GetString("Menu_" + func.FunctionId),
        });
    }
    return newList;
}

Кто-нибудь может помочь? Это так странно!
