我在AutoMapper里用的InstancePerRequest作为生命周期，但是会报错 我按照http://docs.autofac.org/en/latest/faq/per-request-scope.html，这里说的实现了ILifetimeScopeProvider接口SimpleLifetimeScopeProvider ，并且在初始化的时候注册了 var provider= new SimpleLifetimeScopeProvider(container); var resolver = new AutofacDependencyResolver(container, provider); DependencyResolver.SetResolver(resolver); 依旧不行，这是为什么，应该怎么弄？ |

自己看看那里写错了吧
|
|
|
那里=哪里
|
|
|
郁闷，原来要AutofacDependencyResolver.Current.RequestLifetimeScope.Resolve<T>() 这么用。 |
