Introduction to using Managed Identity to authenticate to Azure OpenAI in Microsoft Foundry Models with .NET: Review

That .NET code snippet is a picture of code. Without a sandbox to try it in, it’s useless. They expect you to already have a .NET project, an Azure subscription, and a deployed OpenAI resource just to follow along conceptually. There's no lab, no code to run. You just read about RBAC roles and managed identity, then answer a few multiple-choice questions that barely require reading the page.

I was hoping this would walk me through setting up a secure connection from scratch, maybe with a small, self-contained exercise. Instead, it feels like stumbling into the middle of someone else's project meeting. They list the built-in roles like 'Cognitive Services OpenAI User' and show the JSON for a role definition, which is useful, I guess. But the core task of actually assigning the identity and seeing it work is left as an exercise for the reader... with their own credit card on file.

This isn't for learning. It's for someone who already knows 90% of the process and just needs to look up the exact role name or see a sample app registration call. If you're a student trying to understand how this works, you'll be more confused than when you started. A YouTube video would be a better use of 15 minutes.
