Introduction to messagging with RabbitMQ & C#

Demos for the UGIdotNET "Introduction to messaging with RabbitMQ & C#" Small Talk

Requirements

The following requirements must be met in order to successfully run the demos:

• Visual Studio Code and the Remote container extension.
• Docker must be pre-installed on the machine.
• The repository devcontainer setup requires docker-compose to be installed on the machine.

How to configure Visual Studio Code to run the demos

• Clone the repository
  • On Windows make sure to clone on short path, e.g. c:\dev, to avoid any "path too long" error
• Open the repository root folder in Visual Studio Code
• Make sure Docker is running
  • If you're using Docker for Windows with Hyper-V make sure that the cloned folder, or a parent folder, is mapped in Docker
• Open the Visual Studio Code command palette (F1 on all supported operating systems, for more information on VS Code keyboard shortcuts refer to this page)
• Type Reopen in Container, the command palette supports auto-completion, the command should be available by typing reop

Wait for Visual Studio Code Remote container extension to:

• download the required container images
• configure the docker environment
• configure the remote Visual Studio Code instance with the required extensions

Note: no changes will be made to your Visual Studio Code installation, all changes will be applied to the VS Code instance running in the remote container

The repository devcontainer configuration will:

• One or more container instances:
  • One RabbitMQ instance with management plugin support
  • One .NET 6 enabled container where the repository source code will be mapped
• Configure the VS Code remote instance with:
  • The C# extension (ms-dotnettools.csharp)
  • Bash as the default terminal

Once configuration is completed VS Code will show a new Ports tab, in the bottom-docked terminal area. The Ports tab will list all the ports exposed by the remote containers.

Verify that setup completed successfully

Locate Visual Studio Code Ports tab. The tab by default shows four columns, Port, Local Address, Running Process, and Origin.

• Locate the row, in the Port column, containing the value 15672 (the RabbitMQ management port).
• Hover the located row with the mouse and click on the Open in Browser icon in the Local Address column.
• A new browser tab is opened and the RabbitMQ management page is displayed.

The following section contains connection information details.

Containers connection information

The default RabbitMQ credentials are:

• Username: guest
• Password: guest
