Responsibilities

IAsyncRestPublisher

Responsible for:

• creating requests;
• publishing messages;
• waiting for responses;
• correlating responses.

---

RabbitMQ

Responsible for:

• transporting requests;
• transporting responses;
• buffering messages.

---

RestHostSubscriberBound

Responsible for:

• consuming request messages;
• translating messages into ASP.NET Core requests;
• invoking the ASP.NET Core pipeline;

    Host->>ASPNET: Execute Pipeline

    Host->>RabbitMQ: Publish Response

    RabbitMQ-->>Publisher: Deliver Response

The publisher experiences a request/response interaction while RabbitMQ remains the transport layer.
