This is the first time I've used interceptors with the fluent registration and I'm missing something. With the following registration, I can resolve an IProcessingStep, and it's a proxy class and the interceptor is in the __interceptors array, but for some reason, the interceptor is not called. Any ideas what I'm missing?
Thanks,
Drew
