SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents runtime misconfiguration and secret mishandling by guiding you to build strongly-typed, validated configuration for .NET applications.

Core Features & Use Cases

  • Options pattern with validation: Bind configuration sections to strongly-typed option classes using validation attributes and fail fast at startup.
  • Correct lifetime choice for configuration: Use IOptions for immutable values, IOptionsSnapshot for request-scoped reload scenarios, and IOptionsMonitor for continuously tracked changes.
  • Secure secrets management by environment: Keep secrets out of source control using user secrets for development and Azure Key Vault or environment variables for production.
  • Configuration layering and overrides: Apply appsettings layering rules so later sources override earlier ones reliably across environments.

Quick Start

Load this skill and apply the Options pattern to bind and validate your configuration sections, then source secrets from user-secrets in development and Azure Key Vault or environment variables in production.

Frequently Asked Questions about configuration

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate .NET configuration on startup using the Options pattern?▼

Validate .NET configuration on startup by binding appsettings sections to strongly typed option classes with validation attributes, then enabling ValidateDataAnnotations and ValidateOnStart to fail fast before the application runs.

What is the difference between IOptions, IOptionsSnapshot, and IOptionsMonitor for configuration binding?▼

IOptions provides immutable singleton values, IOptionsSnapshot supports request-scoped configuration reload, and IOptionsMonitor tracks configuration changes continuously for real-time updates across your .NET application.

How do I keep secrets out of appsettings.json in a .NET application?▼

Keep secrets out of source control by using user secrets for local development, and sourcing production secrets securely from environment variables or Azure Key Vault instead of hardcoding them in appsettings.json.

Why should I avoid direct IConfiguration access in my .NET services?▼

Avoid direct IConfiguration access to prevent runtime misconfiguration by using the Options pattern, which binds sections to strongly typed classes and validates settings at startup for safer dependency injection.

How do appsettings layering and overrides work across different environments?▼

Appsettings layering applies multiple configuration sources where later sources override earlier ones, ensuring environment-specific settings reliably replace base configurations without manual intervention.

Can I use Azure Key Vault with .NET configuration binding for production secrets?▼

Yes, you can use Azure Key Vault as a production secret source alongside environment variables, binding retrieved secrets to strongly typed option classes with startup validation for secure .NET configuration.
