SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you configure .NET 10 apps in a reliable, secure, and maintainable way by preventing stringly-typed configuration access, ensuring secrets are handled correctly, and validating configuration at startup.

Core Features & Use Cases

  • Options pattern with strong validation: Bind configuration sections to validated options classes so invalid settings fail fast before runtime.
  • Correct choice of options lifetime: Use IOptions for static config, IOptionsSnapshot for request-scoped reloadable config, and IOptionsMonitor for actively changing config.
  • Environment-aware secrets and layering: Apply consistent configuration layering (appsettings.json, environment overrides, environment variables, user secrets) and route secrets to user-secrets, environment variables, or Key Vault.

Use case example: When deploying a POS-style .NET application across dev, staging, and production, bind the database connection and related settings to a validated options class so misconfigured connection strings are caught immediately and secrets never land in source control.

Quick Start

Bind your required configuration section to a strongly-typed options class using the Options pattern with validation and startup validation, then inject IOptions into the services that need it.

FAQPage Schema
How do I validate .NET configuration at startup to fail fast on invalid settings?

Validate .NET configuration at startup by using AddOptions<T> with BindConfiguration, ValidateDataAnnotations, and ValidateOnStart. This binds configuration sections to strongly-typed options classes, ensuring invalid settings fail before runtime.

What is the difference between IOptions, IOptionsSnapshot, and IOptionsMonitor in .NET?

IOptions provides static configuration, IOptionsSnapshot offers request-scoped reloadable configuration, and IOptionsMonitor handles actively changing configuration. Select the correct interface to match the intended configuration lifetime for your .NET application.

How do I manage secrets and environment-specific configuration in a .NET application?

Manage secrets and layer configuration in .NET by applying consistent layering across appsettings.json, environment overrides, environment variables, and user secrets. Route sensitive data to user-secrets, environment variables, or Key Vault to keep secrets out of source control.

What is the options pattern in .NET and why should I use it instead of IConfiguration?

The options pattern in .NET replaces direct IConfiguration access with validated, strongly-typed options binding. It prevents stringly-typed configuration access, ensures settings are handled securely, and validates configuration at startup for maintainable code.

Can I bind a configuration section to a strongly-typed class in .NET?

Yes, you can bind a configuration section to a strongly-typed class in .NET using AddOptions<T> with BindConfiguration. This allows you to inject the bound options into services, ensuring type safety and consistent configuration loading.

Why should I use startup validation for .NET app configuration?

Startup validation for .NET app configuration catches misconfigured settings, like invalid connection strings, immediately before the application runs. Using ValidateOnStart ensures invalid configurations fail fast, preventing runtime errors across dev, staging, and production environments.
