WPF-Einheit Aktivierungsfehler beim Versuch, eine Instanz des Typs

Question

Ich erhalte den folgenden Fehler, wenn ich versuche, das Modul mit Unity und Prism zu initialisieren. Die DLL wird gefunden durch

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

Die DLL ist gefunden und der Name ist gefunden

  #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

ist der Code, der den Fehler verursacht:

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
        }

Kann mir jemand helfen?
