Microsoft Extensions Configuration Patterns
Implements robust, strongly-typed configuration patterns for .NET applications using Microsoft.Extensions.Options.
This skill provides comprehensive guidance on the .NET Options pattern, enabling developers to bind appsettings.json to POCO classes with built-in validation. It focuses on the 'fail-fast' principle by enforcing configuration checks at application startup via IValidateOptions and ValidateOnStart(), preventing common runtime errors like null reference exceptions from missing settings. It covers basic binding, data annotations, complex cross-property validation, and managing configuration lifetimes with IOptionsMonitor and IOptionsSnapshot.
