autofac无法解析一例

在asp.net mvc分项目开发中，如果类库位于其他的项目中，则必须在global中对其他项目的类库进行注册，否则会报“

None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'SportsStore.WebUI.Controllers.ListController' can be invoked with the available services and parameters:
Cannot resolve parameter 'SportsStore.Domain.Abstrace.IProductRepository productRepository' of constructor 'Void .ctor(SportsStore.Domain.Abstrace.IProductRepository)'.”

解决方案很简单，注册就行。

ContainerBuilder builder = new ContainerBuilder();
            builder.RegisterControllers(Assembly.GetExecutingAssembly());
            builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly()).AsImplementedInterfaces();
            //注册类库程序集
            builder.RegisterAssemblyTypes(Assembly.Load("SportsStore.Domain")).AsImplementedInterfaces();

            var container = builder.Build();
            DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

注：通过nuget 安装Autofac.mvc4
