add-options-class

Adds a typed options/configuration class.

Steps

1. Create in the appropriate layer:
   • Infrastructure: src/backend/MyProject.Infrastructure/{Area}/Options/{Name}Options.cs
   • WebApi: src/backend/MyProject.WebApi/Options/{Name}Options.cs
2. Structure:

   /// <summary>
   /// Configuration for {area}. Maps to "{SectionName}" in appsettings.json.
   /// </summary>
   public sealed class {Name}Options
   {
       public const string SectionName = "{Section}";
   
       /// <summary>
       /// Gets or sets the ...
       /// </summary>
       [Required]
       public string Value { get; init; } = string.Empty;
   }

3. Add section to appsettings.json (and appsettings.Development.json if dev differs - dev/test appsettings excluded from production publish via StripDevConfig)
4. Register in DI extension:

   services.AddOptions<{Name}Options>()
       .BindConfiguration({Name}Options.SectionName)
       .ValidateDataAnnotations()
       .ValidateOnStart();

5. Update docs/before-you-ship.md if this is a must-configure production setting
