I am testing out the Req/Res Filter Attributes on the ToDo List sample project with the code above. So nothing else has been changed to the sample project (I think) except for the two additional attributes.

When I add a todo item, only the request attribute was called. The response attribute didn't get triggered.

Shouldn't they fire up in a pair before & after a Rest call in this case? Is my understanding incorrect or am I doing something wrong? Thank you ahead for your help.

Use your request and response filters with respective Request and Response DTO

    [Route("/Hello")]
    [RequestAspect]
    public class HelloRequest
    {
        public string hello { get; set; }
    }
    [ResponseAspect]
    public class HelloResponse
    {
        public string hello { get; set; }
    }
    public class HelloService : Service
    {
        public object Any(HelloRequest req)
        {
            return new HelloResponse
            {
                hello = req.hello
            };
        }
    }
