无法构建 Unity 容器 - Prism

Question

我正尝试在我的 WPF 应用程序中使用 prism。到目前为止，我已经像这样配置了我的容器和视图模型定位器：

   protected override void ConfigureContainer()
    {



        Container.RegisterType<IEventAggregator, EventAggregator>(new ContainerControlledLifetimeManager());
        Container.RegisterType<IUnitOfWork, UnitOfWork>();
        Container.RegisterType<IDbFactory, DbFactory>();
        Container.RegisterType<IUnitOfWork, UnitOfWork>("UnitOfWork", new ContainerControlledLifetimeManager());
        Container.Resolve<IUnitOfWork>("UnitOfWork");
        Container.RegisterType<IDbFactory, DbFactory>("DbFactory", new ContainerControlledLifetimeManager());
        Container.Resolve<IDbFactory>("DbFactory");
        Container.RegisterType<IRegionManager, RegionManager>();
        Container.RegisterInstance<IRegionManager>(new RegionManager(), new ContainerControlledLifetimeManager());


        #region Register Repositories

        Container.RegisterType<IVendorRepository, VendorRepository>();

        Container.RegisterType<IUserRepository, UserRepository>();
        Container.RegisterType<IReceiveablesRepository, ReceiveablesRepository>();
        Container.RegisterType<IProductUnitsRepository, ProductUnitRepository>();
        Container.RegisterType<IPaymentRepository, PaymentRepository>();
        Container.RegisterType<IItemRepository, ItemRepository>();
        Container.RegisterType<IInvoiceMasterRepository, InvoiceMasterRepository>();
        Container.RegisterType<IInvoiceDetailRepository, InvoiceDetailRepository>();
        Container.RegisterType<IExpenseTypeRepository, ExpenseTypeRepository>();
        Container.RegisterType<IExpenseRepository, ExpenseRepository>();
        Container.RegisterType<ICustomerRepository, CustomerRepository>();
        Container.RegisterType<ICategoryRepository, CategoryRepository>();
        Container.RegisterType<IAddressesRepository, AddressesRepository>();
        #endregion
        #region Register Services

        Container.RegisterType<IVendorService, VendorService>();
        Container.RegisterType<IUserService, UserService>();
        Container.RegisterType<IReceiveablesService, ReceiveablesService>();
        Container.RegisterType<IProductUnitService, ProductUnitService>();
        Container.RegisterType<IPaymentService, PaymentService>();

        Container.RegisterType<IItemService, ItemService>();
        Container.RegisterType<InvoiceMasterService, InvoiceMasterService>();
        Container.RegisterType<IInvoiceDetailService, InvoiceDetailService>();
        Container.RegisterType<IExpenseTypeService, ExpenseTypeService>();
        Container.RegisterType<IExpenseService, ExpenseService>();
        Container.RegisterType<ICustomerService, CustomerService>();
        Container.RegisterType<ICategoryService, CategoryService>();
        Container.RegisterType<IAddressesService, AddressesService>();

        #endregion

        Container.RegisterType<IDbFactory, DbFactory>("DbFactory", new InjectionConstructor());
        Container.RegisterType<IUnitOfWork, UnitOfWork>();
        Container.RegisterType<IDbFactory, DbFactory>();
        //Container.RegisterType<IService, >();
        Container.RegisterType<IEventAggregator, EventAggregator>(new PerThreadLifetimeManager());

        Container.RegisterTypeForNavigation<Billing>();
        Container.RegisterTypeForNavigation<Sales>();
        Container.RegisterTypeForNavigation<Management>();
        Container.RegisterTypeForNavigation<Home>();
        Container.RegisterTypeForNavigation<Orders>();
        Container.RegisterTypeForNavigation<Purchases>();



    }
   protected override void ConfigureViewModelLocator()
    {
        base.ConfigureViewModelLocator();
        Container.RegisterInstance(new DbFactory());
        Container.RegisterInstance(new UnitOfWork(Container.Resolve<DbFactory>()));
        Container.RegisterType<IEventAggregator, EventAggregator>(new ContainerControlledLifetimeManager());
        Container.RegisterType<IRegionManager, RegionManager>();
        Container.RegisterInstance(new UserRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new UserService(Container.Resolve<UnitOfWork>(),Container.Resolve<UserRepository>()));
        Container.RegisterInstance(new VendorRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new VendorService(Container.Resolve<UnitOfWork>(),Container.Resolve<VendorRepository>()));
        Container.RegisterInstance(new ReceiveablesRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new ReceiveablesService(Container.Resolve<UnitOfWork>(),Container.Resolve<ReceiveablesRepository>()));
        Container.RegisterInstance(new ProductUnitRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new ProductUnitService(Container.Resolve<UnitOfWork>(), Container.Resolve<ProductUnitRepository>()));
        Container.RegisterInstance(new PaymentRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new PaymentService(Container.Resolve<UnitOfWork>(), Container.Resolve<PaymentRepository>()));
        Container.RegisterInstance(new ItemRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new ItemService(Container.Resolve<UnitOfWork>(), Container.Resolve<ItemRepository>()));
        Container.RegisterInstance(new InvoiceMasterRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new InvoiceMasterService(Container.Resolve<UnitOfWork>(), Container.Resolve<InvoiceMasterRepository>()));
        Container.RegisterInstance(new InvoiceDetailRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new InvoiceDetailService(Container.Resolve<UnitOfWork>(), Container.Resolve<InvoiceDetailRepository>()));
        Container.RegisterInstance(new ExpenseRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new ExpenseService(Container.Resolve<UnitOfWork>(), Container.Resolve<ExpenseRepository>()));
        Container.RegisterInstance(new ExpenseTypeRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new ExpenseTypeService(Container.Resolve<UnitOfWork>(), Container.Resolve<ExpenseTypeRepository>()));
        Container.RegisterInstance(new CustomerRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new CustomerService(Container.Resolve<UnitOfWork>(), Container.Resolve<CustomerRepository>()));
        Container.RegisterInstance(new CategoryRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new CategoryService(Container.Resolve<UnitOfWork>(), Container.Resolve<CategoryRepository>()));
        Container.RegisterInstance(new AddressesRepository(Container.Resolve<DbFactory>()),new ContainerControlledLifetimeManager());
        Container.RegisterInstance(new AddressesService(Container.Resolve<UnitOfWork>(), Container.Resolve<AddressesRepository>()));
        Container.RegisterType<IRegionManager, RegionManager>();
        Container.RegisterInstance<IRegionManager>(new RegionManager(), new ContainerControlledLifetimeManager());



        ViewModelLocationProvider.SetDefaultViewModelFactory((o, type) => Container.Resolve(type));
    }

在此之后，当我尝试 运行 我的应用程序时，它在 bootstrap.run() 上崩溃并抛出以下异常：

Resolution of the dependency failed, type = "Microsoft.Practices.ServiceLocation.IServiceLocator", name = "(none)". Exception occurred while: while resolving.

Exception is: InvalidOperationException - The current type, Microsoft.Practices.ServiceLocation.IServiceLocator, is an interface and cannot be constructed. Are you missing a type mapping?

At the time of the exception, the container was:

Resolving Microsoft.Practices.ServiceLocation.IServiceLocator,(none)

Answer 1

您收到错误的原因是您使用的版本不兼容。 Prism 6.3 是针对 Unity 4.0.1 和 CommonServiceLocator 1.3.0 构建的。较新版本的 CommonServiceLocator 和 Unity 包含一些使其与 Prism 6.3 不兼容的重大更改，包括命名空间的更改。

请更新到 Prism 7 预览版以兼容 Unity 5 和 CommonServiceLocator 2。您可以在 Prism 7 本身中获得完整的更改列表 here。我要说的是，我们添加了许多重大更改，特别是在 WPF 的最新预览版中。
