操作方法：Caliburn.Micro.Autofac 和 Windows Phone

Question

是否有示例、教程或任何内容展示如何在 Windows Phone 中使用 Caliburn.Micro.Autofac？

我仅使用 Caliburn.Micro 创建了一个基本应用程序，并且运行良好。然后我决定使用 Caliburn.Micro.Autofac，因此我从 Caliburn.Micro.Autofac.AutofacBootstrapper 派生了我的 Bootstrapper，并在 Bootstrapper 中调用 base.Configure() >Configure() 方法。现在，当我运行该应用程序时，我得到“未找到类型‘AppBootstrapper’”。例外。

感谢任何帮助。

这是我为 WP7 项目编写的引导程序。它基于 Caliburn.Micro.Autofac.AutofacBootstrapper 但修复了一些错误。

public class AppBootstrapper : PhoneBootstrapper
{
    private IContainer container;

    protected void ConfigureContainer(ContainerBuilder builder)
    {
        // put any custom bindings here
    }

    #region Standard Autofac/Caliburn.Micro Bootstrapper

    protected override void Configure()
    {
        //  configure container
        var builder = new ContainerBuilder();

        //  register phone services
        var caliburnAssembly = AssemblySource.Instance.Union(new[] { typeof(IStorageMechanism).Assembly }).ToArray();
        //  register IStorageMechanism implementors
        builder.RegisterAssemblyTypes(caliburnAssembly)
          .Where(type => typeof(IStorageMechanism).IsAssignableFrom(type)
                         && !type.IsAbstract
                         && !type.IsInterface)
          .As<IStorageMechanism>()
          .SingleInstance();

        //  register IStorageHandler implementors
        builder.RegisterAssemblyTypes(caliburnAssembly)
          .Where(type => typeof(IStorageHandler).IsAssignableFrom(type)
                         && !type.IsAbstract
                         && !type.IsInterface)
          .As<IStorageHandler>()
          .SingleInstance();

        // The constructor of these services must be called
        // to attach to the framework properly.
        var phoneService = new PhoneApplicationServiceAdapter(RootFrame);
        var navigationService = new FrameAdapter(RootFrame, false);

        builder.Register<IPhoneContainer>(c => new AutofacPhoneContainer(c)).SingleInstance();
        builder.RegisterInstance<INavigationService>(navigationService).SingleInstance();
        builder.RegisterInstance<IPhoneService>(phoneService).SingleInstance();
        builder.Register<IEventAggregator>(c => new EventAggregator()).SingleInstance();
        builder.Register<IWindowManager>(c => new WindowManager()).SingleInstance();
        builder.Register<IVibrateController>(c => new SystemVibrateController()).SingleInstance();

        builder.RegisterType<StorageCoordinator>().AsSelf().SingleInstance();
        builder.RegisterType<TaskController>().AsSelf().SingleInstance();

        //  allow derived classes to add to the container
        ConfigureContainer(builder);

        //  build the container
        container = builder.Build();

        //  start services
        container.Resolve<StorageCoordinator>().Start();
        container.Resolve<TaskController>().Start();

        //  add custom conventions for the phone
        AddCustomConventions();
    }

    protected override object GetInstance(Type service, string key)
    {
        object instance;
        if (string.IsNullOrEmpty(key))
        {

        }
        throw new Exception(string.Format("Could not locate any instances of contract {0}.", key ?? service.Name));
    }

    protected override IEnumerable<object> GetAllInstances(Type service)
    {
        return container.Resolve(typeof(IEnumerable<>).MakeGenericType(service)) as IEnumerable<object>;
    }

    protected override void BuildUp(object instance)
    {
        container.InjectProperties(instance);
    }

    private static void AddCustomConventions()
    {
        ConventionManager.AddElementConvention<Pivot>(Pivot.ItemsSourceProperty, "SelectedItem", "SelectionChanged").ApplyBinding =

                return false;

编辑 我创建了 Caliburn.Micro.Autofac 的一个分支，并在 GitHub 上修复了该问题。希望拉取请求能够被接受，并且这将成为主存储库的一部分。

现在，您可以从此处访问引导程序和 AutofacPhoneContainer - https://github.com/distantcam/Caliburn.Micro.Autofac/tree/master/src/Caliburn.Micro.Autofac-WP7

Answer 2

我已经为 Windows Phone 实现了 Caliburn.Micro.Autofac 的正确版本（在我看来）。您可以从我的博客下载它并测试项目。该博文是俄语的，但您可以在博文顶部找到 ZIP 文件的链接。代码太大，无法在此处发布，因此请从博客中获取。我已将其发送给 David Buksbaum（Caliburn.Micro.Autofac 的作者）。希望他尽快将其合并到他的代码库中。

更新

修复内容：

1. 实现 IPhoneService 和 INavigationService 服务的组件必须在注册到容器中之前实例化。
2. 实现了IPhoneContainer的组件。没有它，您将无法在 Caliburn.Micro 中使用 Autofac。
