如何: Caliburn.Micro.Autofac和Windows

Question

是否有说明如何在Windows中使用Caliburn.Micro.Autofac的示例、教程或任何内容？

我只使用Caliburn.Micro创建了一个基本应用程序，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Bootstrapper，并在Bootstrapper Configure()方法中调用了base.Configure()。现在，我运行了一个应用程序，我得到了“找不到'AppBootstrapper‘类型’”。异常。

感谢你的帮助。

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bug。

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.Register<ISoundEffectPlayer>(c => new XnaSoundEffectPlayer()).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))
        {
            if (container.TryResolve(service, out instance))
                return instance;
        }
        else
        {
            if (container.TryResolveNamed(key, service, out instance))
                return instance;
        }
        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 =
            (viewModelType, path, property, element, convention) =>
            {
                if (ConventionManager

                }

                return false;

            {

                {

编辑我创建了一个Caliburn.Micro.Autofac分叉，并在GitHub上解决了这个问题。希望拉请求将被接受，这将成为主要存储库的一部分。

现在，您可以从这里访问引导程序和AutofacPhoneContainer - https://github.com/distantcam/Caliburn.Micro.Autofac/tree/master/src/Caliburn.Micro.Autofac-WP7。

Answer 2

我已经为Windows实现了一个正确的Caliburn.Micro.Autofac版本(在我看来)。您可以从我的博客下载并测试项目。博客文章是用俄语写的，但是你可以在文章的顶部找到指向ZIP文件的链接。代码太大了，不能在这里发布，所以请从博客中获取。我已将此发送给David (Caliburn.Micro.Autofac的作者)。希望他能很快把它整合到他的代码库中。

更新

固定的是：

1. 在容器中注册之前，必须实例化实现IPhoneService和INavigationService服务的组件。
2. 实现了实现IPhoneContainer的组件。没有它，您就不能在Caliburn.Micro中使用Autofac。
