Prism 8 支持 Autofac

Question

我们有一个使用 Autofac 的大项目。我们还在该项目中使用了 Prism EventAggregator 和 DelegateCommand。我们需要在这个项目中使用区域和模块。我读到，除非我没有理解，棱镜不再支持 Autofac。如果 Prism 8 支持使用 Autofac 的方式，或者它会卡在 Unity 和 DryIOC 中，有人会友善地告诉我吗？

提前致谢？赛菲

我在 Prism 7 中遇到了类似的问题，我最终将 Prism.Unit.PrismApplication 用于 App.xaml.cs。但对于其余服务，我能够使用 Autofac。覆盖了 ConfigureModuleCatalog

 protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog)
        {
            base.ConfigureModuleCatalog(moduleCatalog);
            moduleCatalog.AddModule<MyModule>();

            Bootstrapper.Run(this, new List<AutofacModuleBase>()
                                {
                                    // autofac modules
                                });

        }

public class Bootstrapper
{
    public static void Run(PrismApplicationBase prismApplicationBase,
        List<AutofacModuleBase> modules)
    {
       // other codes
        ContainerBuilder builder = new ContainerBuilder();            
        builder.RegisterModule(new ClientApplicationPrismModule(prismApplicationBase.Container));
        foreach (AutofacModuleBase autofacModuleBase in modules)
        {
            builder.RegisterModule(autofacModuleBase);
        }

        IContainer containerBuild = builder.Build();
        ServiceManager.Instance.SetContainerDirty(containerBuild);
       // other codes
    }

}

从 Autofac 解析

public class ClientApplicationPrismModule : AutofacModuleBase
{
    public ClientApplicationPrismModule(IContainerProvider container)
    {
        Container = container;
    }

    public IContainerProvider Container { get; set; }

    protected override void Load(ContainerBuilder builder)
    {
        RegisterTypeSpecial<IDialogService>(builder);
        RegisterTypeSpecial<IDialogWindow>(builder);
        RegisterTypeSpecial<IModuleInitializer>(builder);
        RegisterTypeSpecial<IModuleManager>(builder);
        RegisterTypeSpecial<RegionAdapterMappings>(builder);
        RegisterTypeSpecial<IRegionManager>(builder);
        RegisterTypeSpecial<IEventAggregator>(builder);
        RegisterTypeSpecial<IRegionViewRegistry>(builder);
        RegisterTypeSpecial<IRegionBehaviorFactory>(builder);
        RegisterTypeSpecial<IRegionNavigationJournalEntry>(builder);
        RegisterTypeSpecial<IRegionNavigationJournal>(builder);
        RegisterTypeSpecial<IRegionNavigationService>(builder);
        RegisterTypeSpecial<IRegionNavigationContentLoader>(builder);
        RegisterTypeSpecial<IContainerExtension>(builder, false);
    }

    protected void RegisterTypeSpecial<TFrom>(ContainerBuilder builder, bool isSingleInstace = true)
    {
        IRegistrationBuilder<TFrom, SimpleActivatorData, SingleRegistrationStyle> registration 
            = builder.Register((comp) =>
        {
            TFrom service = Container.Resolve<TFrom>();
            return service;
        }).As<TFrom>()
            .IfNotRegistered(typeof(TFrom));

        if (isSingleInstace)
        {
            registration.SingleInstance();
        }
    }
}

prism 8官方不支持autofac，你只能使用autofac直到prism 7。但是prism提供了关于如何添加自定义容器的说明：

Prism 8 支持 Autofac
