Get TenantId for any Azure Subscription

How I Used GitHub Copilot to Write a PowerShell GUI for Azure Tenant ID Lookup

When tasked with creating a PowerShell GUI to retrieve the Azure Tenant ID for any subscription, I decided to rely entirely on GitHub Copilot. Here’s how I did it—without manually writing a single line of code myself. (repo -> https://github.com/gsuttie/getTenantIdFromAzureSubscriptionId)

Setting Up

1. Open Visual Studio Code: My preferred development environment. I enabled GitHub Copilot for code suggestions.
2. Define Goals:
   • A user-friendly GUI for inputting an Azure Subscription ID.
   • Backend logic to retrieve the Tenant ID using Azure PowerShell.
   • Automatically generate inline documentation and a comprehensive README file.

Prompting GitHub Copilot

• I started by creating a new PowerShell file and inputting the following prompt for Copilot:Create a PowerShell script for a GUI that accepts an Azure Subscription ID, retrieves the Tenant ID using `Get-AzSubscription`, and displays it. Include inline comments and generate a README.
• I then tweeked the prompt a few times and the end result can be found in the following GitHub repo

Documentation and README

I added another comment to the script:

Generate a README file explaining the purpose of this script, its usage, prerequisites, and examples.

Copilot produced a structured README covering:

• Purpose: Explaining the script’s function.
• Usage: Step-by-step instructions on running the script.
• Prerequisites: Details about Azure PowerShell modules and authentication requirements.
• Example: A sample input and output demonstration.

Testing and Tweaking

I tested the script on a sample Azure environment. While functional, the GUI layout needed minor adjustments. I prompted Copilot with:

Improve the alignment and spacing of GUI elements.

This fine-tuned the interface, making it visually cleaner.

Final Output

With GitHub Copilot, I:

• Built a functional PowerShell GUI to retrieve Azure Tenant IDs.
• Included inline comments and documentation.
• Generated a detailed README without writing any code manually.

Summary

GitHub Copilot significantly accelerated the development process. While it handled 95% of the work, reviewing and testing were key to ensuring functionality and usability. This approach is ideal for tasks where speed and automation are priorities.
