Question

我是通过ASP.NET MVC 3的DI新手。我使用mefcontrib作为我的DI容器。我通过nuget安装了mefcontrib和mefcontrib.mvc3。当我尝试运行该项目时，我收到此错误：

IControllerFactory 'mefContrib.Web.Mvc.CompositionControllerFactory'没有返回控制器名为'Home'。

我用Google搜索错误并再次搜索和搜索。但我找不到任何东西！大家可以帮帮我吗？这是nuget自动创建的App_Start内容：

[assembly: WebActivator.PreApplicationStartMethod(typeof(AlamKouh.UI.App_Start.AppStart_MefContribMVC3), "Start")]

namespace AlamKouh.UI.App_Start
{
    using System.ComponentModel.Composition.Hosting;
    using System.Linq;
    using System.Web.Mvc;
    using MefContrib.Hosting.Conventions;
    using MefContrib.Web.Mvc;

    public static class AppStart_MefContribMVC3
    {
        public static void Start()
        {
            CompositionContainerLifetimeHttpModule.Register();

            var catalog = new AggregateCatalog(
                new DirectoryCatalog("bin"),
                new ConventionCatalog(new MvcApplicationRegistry()));

            var dependencyResolver = new CompositionDependencyResolver(catalog);
            DependencyResolver.SetResolver(dependencyResolver);

            ControllerBuilder.Current.SetControllerFactory(
                new CompositionControllerFactory(
                    new CompositionControllerActivator(dependencyResolver)));

            FilterProviders.Providers.Remove(FilterProviders.Providers.Single(f => f is FilterAttributeFilterProvider));
            FilterProviders.Providers.Add(new CompositionFilterAttributeFilterProvider(dependencyResolver));

            ModelValidatorProviders.Providers.Remove(ModelValidatorProviders.Providers.OfType<DataAnnotationsModelValidatorProvider>().Single());
            ModelValidatorProviders.Providers.Add(
                new CompositionDataAnnotationsModelValidatorProvider(dependencyResolver));

            ModelBinderProviders.BinderProviders.Add(
                new CompositionModelBinderProvider(dependencyResolver));
        }
    }
}

这是我的HomeController：

namespace AlamKouh.UI.Controllers {

    public interface ITest<T> { }

    [Export(typeof(ITest<>))]
    public class Test<T> : ITest<T> { }

    public class HomeController : Controller {

        private readonly ITest<string> _test;

        [ImportingConstructor]
        public HomeController(ITest<string> test) {
            _test = test;
        }

        public ActionResult Index() {
            var t = _test;
            return View();
        }
    }
}

更新

@Yorgo建议我切换到StructureMap然后我这样做。 StructureMap对我来说更容易，所以我接受@ Yorgo的回答。

Answer 1

最佳和最快的DI容器是StructureMap。我建议你使用它。如果您想使用它，我可以帮助您进行配置

IControllerFactory'MefContrib.Web.Mvc.CompositionControllerFactory'没有返回名称'Home'的控制器
