Count List stays 0 after adding an item and resolving via unity container

Hi Everyone,

I have a small issue but cannot figure out to get it working.
I have a windows Service and each minute it does some tasks.
To test if I can store all my exceptions in memory (and later send them to a database as soon as a disconnect db is connected again).
In the class holding the List<encouteredexceptions> is see the exception is added.

In the service1.cs file I have:

private IUnityContainer _container;
       private MainService _service;
       public srvBackground()
       {
           InitializeComponent();
           _container = new UnityContainer();
           _container.RegisterType<IExceptions, Exceptions>("EncounteredExceptions", new ContainerControlledLifetimeManager());
           _service = new MainService();
       }

In my LogData class I have:

_exceptions = _container.Resolve<Exceptions>("EncounteredExceptions");

The Exceptions class holds:

private EncounteredException _encounteredException;

        private List<EncounteredException> _exceptionsList = new List<EncounteredException>();
        public List<EncounteredException> ExceptionsList
        {
            get { return _exceptionsList ?? (_exceptionsList = new List<EncounteredException>()); }
        }

        public Exceptions()
        {
        }

        public void Add(Exception exception)
        {
            try
            {
                _encounteredException = new EncounteredException();
                _encounteredException.exception = exception;
                _encounteredException.exceptionProcessedToDatabase = false;
                _encounteredException.excptionOccurred = DateTime.Now;
                _exceptionsList.Add(_encounteredException);
            }
            catch (Exception err)
            {
                // ToDO
            }
        }

How I have to Update the unity Container so that a Resolve in another class would give me the EncounteredExceptions list?
