- channel.TypedReceiveHandler -> channel.ContentTypeReceiver - binding.AddTypedReceiveHandler(h) -> channel.AddReceiveHandlers(binding, h) channel/v5 repurposes TypedReceiveHandler for the senders-typed handler and replaces the self-describing pattern with ContentTypeReceiver plus the AddReceiveHandlers free function (openziti/channel#262). Mechanical conversion; does not build on its own.
