Answer
Configuration is layered: appsettings.json, environment configs, secrets, environment variables, command-line args. Supports reload-on-change and strongly typed bindings.
Quick Answer
Multiple configuration sources layer together: JSON files, environment variables, User Secrets, Azure Key Vault. Values from later sources override earlier ones. IConfiguration provides the unified API. The system is composable — you can add custom providers for any config source. Strongly-typed options classes (IOptions) are the recommended way to consume configuration.
