Произошла ошибка активации WPF unity при попытке получить экземпляр типа

я получаю следующую ошибку при попытке инициализировать модуль с помощью Unity и Prism. DLL находится по

return new DirectoryModuleCatalog() { ModulePath = @".Modules" };

dll найдена, и имя найдено

  #region Constructors

    public AdminModule(
        IUnityContainer container,
        IScreenFactoryRegistry screenFactoryRegistry,
        IEventAggregator eventAggregator,
        IBusyService busyService
        )
        : base(container, screenFactoryRegistry)
    {
        this.EventAggregator = eventAggregator;
        this.BusyService = busyService;
    }

    #endregion

    #region Properties

    protected IEventAggregator EventAggregator { get; set; }
    protected IBusyService BusyService { get; set; }

    #endregion

    public override void Initialize()
    {
        base.Initialize();
    }

    #region Register Screen Factories

    protected override void RegisterScreenFactories()
    {
        this.ScreenFactoryRegistry.Register(ScreenKeyType.ApplicationAdmin, typeof(AdminScreenFactory));
    }

    #endregion

    #region Register Views and Various Services

    protected override void RegisterViewsAndServices()
    {
        //View Models
        this.Container.RegisterType<IAdminViewModel, AdminViewModel>();

               }

    #endregion

код, который создает ошибку:

namespace Microsoft.Practices.Composite.Modularity
    protected virtual IModule CreateModule(string typeName)
        {
            Type moduleType = Type.GetType(typeName);
            if (moduleType == null)
            {
                throw new ModuleInitializeException(string.Format(CultureInfo.CurrentCulture, Properties.Resources.FailedToGetType, typeName));
            }

            return (IModule)this.serviceLocator.GetInstance(moduleType); <-- Error Here
        }

Может Кто-Нибудь Мне Помочь
