How does startup validation help my application?

By using ValidateDataAnnotations() and ValidateOnStart(), the application will fail to launch if configuration values are missing or invalid, allowing you to catch misconfigurations immediately rather than at runtime.

What is the difference between IOptions and IOptionsSnapshot?

IOptions is a singleton and read once at startup, while IOptionsSnapshot is scoped and re-evaluates configuration for every request, allowing for dynamic configuration reloading without restarting the app.

Why should I use the Options pattern instead of IConfiguration?

The Options pattern provides strong typing, enables validation at startup, and decouples your classes from the configuration infrastructure, making code much easier to unit test.

How does this skill handle sensitive secrets?

It enforces best practices by using User Secrets for local development and services like Azure Key Vault or environment variables for production, ensuring secrets are never committed to source control.
