Level Method Attributed Interception with Autofac

Question

(This question is related to this , which is for SimpleInjector. I was recommended to create separate questions for each IoC container.)

With Unity, I can quickly add attribute-based interception like this

public sealed class MyCacheAttribute : HandlerAttribute, ICallHandler
{
   public override ICallHandler CreateHandler(IUnityContainer container)
   {
        return this;
   }

   public IMethodReturn Invoke(IMethodInvocation input, GetNextHandlerDelegate getNext)
   {
      // grab from cache if I have it, otherwise call the intended method call..
   }
}

Then I register with Unity as follows:

  container.RegisterType<IPlanRepository, PlanRepository>(new ContainerControlledLifetimeManager(),
           new Interceptor<VirtualMethodInterceptor>(),
           new InterceptionBehavior<PolicyInjectionBehavior>());

In my repository code, I can selectively decorate certain methods that need to be cached (with attribute values ​​that can be individually configured for each method):

    [MyCache( Minutes = 5, CacheType = CacheType.Memory, Order = 100)]
    public virtual PlanInfo GetPlan(int id)
    {
        // call data store to get this plan;
    }

    public sealed class MyCacheAttribute : IInterceptor
    {

        public void Intercept(IInvocation invocation)
        {
            // grab from cache if I have it, otherwise call the intended method call..

            Console.WriteLine("Calling " + invocation.Method.Name);

            invocation.Proceed();
        }
    }

     containerBuilder.RegisterType<PlanRepository>().As<IPlanRepository>().EnableInterfaceInterceptors();
     containerbuilder.RegisterType<MyCacheAttribute>();
