So you mean if I have 50 classes that I want to provide same logger, I’ll have to explicitly register the same interceptor and hook for every class
container.Register(Component.For<LogInterceptor>(), Component.For<LoggingProxyGenerationHook>(), Component.For<ILogger>().ImplementedBy<Logger>(), Component.For<IFoo>().ImplementedBy<Foo>().Interceptors<LogInterceptor>().P¬roxy.Hook( h => h.Service<LoggingProxyGenerationHook>()), Component.For<IMath>().ImplementedBy<Math>().Interceptors<LogInterceptor>(). Proxy.Hook(h => h.Service<LoggingProxyGenerationHook>()), Component.For<ICar>().ImplementedBy<Car>().Interceptors<LogInterceptor>(). Proxy.Hook(h => h.Service<LoggingProxyGenerationHook>()) ); Can’t we configure the container to use the interceptor for all the classes that get resolved by the container? Wouldn’t it be easier and cleaner that way, you don’t have to be repetitive. I can’t remember exactly, but there was mention of sometime similar by creating a facility and registering it, something along those lines?
