Castle Windsor - Releasing Interceptor with Transient Lifestyle

Question

It is stated in the documentation that you should always make interceptors transient. If I have this sample code;

//register interceptor
container.Register(Classes.FromAssemblyNamed("Sample.Interceptors")
.BasedOn<Castle.DynamicProxy.IInterceptor>()
.LifestyleTransient());

//Configure components to intercept
 container.Register(Classes.FromAssemblyNamed("Sample.Component")
.IncludeNonPublicTypes().InNamespace("Sample.Component", true)
            .Configure(c=>
                c.Interceptors(InterceptorReference.ForType<SampleInterceptor>())
                 .Anywhere.LifestyleSingleton())
                 .WithService.DefaultInterfaces()
                );

Should I worry about releasing SampleInterceptor, or will it be released automatically once the service in Sample.Component has been released by the container?

Answer 1

Your transient interceptor will have its lifespan bound to the object you associate it with, and will be released when that object gets released as any other part of that object's graph
