Sample of using Azure Service Bus with .NET

Overview

This sample code demonstrates how to send and receive messages using Azure Service Bus. It consists of two projects: QueueReceiver and QueueSenderAPI. QueueReceiver is a Console Application that listens for messages, while QueueSenderAPI is an ASP.NET Core Web API that sends messages to a queue.

Disclaimer

This code is for demonstration purposes and should not be considered production-ready. It does not adhere to best practices that you would typically use in a production application. It's intended to help you understand the basics of working with Azure Service Bus.

Getting Started

Prerequisites

  • .NET SDK (7.0 or later)
  • Azure Service Bus namespace and connection string

Setup

  1. Clone the Repository: Clone this repository to your local machine.

  2. Set Up Azure Service Bus:

    • If you don't already have an Azure subscription, you can sign up for one on the Azure website.
    • Once you have an Azure subscription, follow the Azure portal's guide to create an Azure Service Bus namespace and obtain the necessary connection information.

  3. Configure QueueReceiver:

    • Open your terminal for the QueueReceiver project.

    • Use the following commands to configure user secrets:

      dotnet user-secrets set "QueueOptions:Connection" "<your_azure_service_bus_connection>"
dotnet user-secrets set "QueueOptions:QueueName" "<your_queue_name>"

  4. Configure QueueSenderAPI:

    • Open the terminal for the QueueSenderAPI project.

    • Use the following commands to configure user secrets:

      dotnet user-secrets set "QueueOptions:Connection" "<your_azure_service_bus_connection>"
dotnet user-secrets set "QueueOptions:QueueName" "<your_queue_name>"

  5. Run the API:

    • In the QueueSenderAPI project, run the API by pressing F5 or using dotnet run.

Sending Messages

  1. Use an API Client:

    • Use an API client (e.g., Postman) to send POST requests to the /messages endpoint of the running API (http://localhost:7231/messages).

  2. Send JSON Data:

    • Send JSON data with author and message fields to create messages.

Receiving Messages

  1. Start QueueReceiver:

    • Start the QueueReceiver console application.

  2. Listening for Messages:

    • The QueueReceiver will listen for incoming messages from the configured Azure Service Bus queue.

  3. Display Messages:

    • Messages will be displayed in the console as they are received.

Stopping the Applications

  • To stop the QueueReceiver, press any key in its console window.
  • To stop the QueueSenderAPI, press Ctrl+C in its console window.
