If I don't add the exported value on my repositories they won't be ignected to my models...

var provider = new EntityManagerProvider();

        var chProvider = new CHEntityManagerProvider();

        var ExportProvider = new ExportEntityManagerProvider();

        var Repository = new myRepository(provider);

        var chRepository = new CHRepository(chProvider);

        var ExportRepository = new ExportRepository(ExportProvider);

        batch.AddExportedValue<IApplicationRepository>(Repository);

        batch.AddExportedValue<ICHApplicationRepository>(chRepository);

        batch.AddExportedValue<IExportRepository>(ExportRepository);

        var admin = new AuthenticationService<Entities>(provider.Manager);

        chProvider.Manager.LinkForAuthentication(provider);

        ExportProvider.Manager.LinkForAuthentication(provider);

        batch.AddExportedValue<IAuthenticationService>(admin);
