In Episode 76 of The Blazor Puzzle, Carl Franklin and Jeff Fritz dive into a real-world developer challenge:

👉 How do you support multiple Blazor environments (like QA, Training, or Client-specific deployments) without constantly renaming JSON files or hacking your code?

Jeff walks through the right way to manage environment-specific configuration using .NET’s built-in appsettings.{Environment}.json pattern, custom environment names (not just "Development" and "Production"), and clever use of environment variables—including in Azure deployments.

🔧 What You'll Learn:
✔️ How to set up and switch between environment-specific config files
✔️ How to pass environment names using launchSettings.json or environment variables
✔️ How to override config settings like feature flags (e.g., AllowWeather)
✔️ How to display a dynamic corner ribbon UI to show which environment you're in
✔️ How to keep your Blazor app clean, multi-environment, and user-aware

🎁 BONUS: Jeff includes a reusable Blazor component (EnvironmentRibbon.razor) to visually mark your environment in the browser!
