You bind appsettings.json sections to strongly-typed C# classes using the .NET Options pattern. This maps configuration values to objects like IOptions<T>, enabling safe, maintainable access to hierarchical settings such as database connection strings.

The best way to manage development secrets outside source control in .NET is using User Secrets. This stores sensitive data like API keys in a local machine profile, keeping them entirely separate from your project directory and repository.

You dynamically enable or disable features using Microsoft.FeatureManagement in .NET. This library integrates with your configuration system to provide feature flags, allowing you to toggle experimental features on or off without redeploying code.

Yes, .NET configuration supports custom validation for strongly-typed options. You can enforce data annotation validation or implement IValidateOptions<T> to check configuration values at startup, preventing invalid settings from crashing the application later.

Your .NET configuration might not update because you are using IOptions<T> instead of IOptionsMonitor<T>. IOptionsMonitor<T> supports reloading of configuration data automatically when underlying sources like appsettings.json change.
