You validate InputModels using FluentValidation by creating specific validator classes for each InputModel to enforce required, length, and format rules before domain logic executes. This approach ensures structural correctness across API inputs, command objects, and use cases within a Clean Architecture setup.

To auto-validate requests in an ASP.NET Core API pipeline, you integrate FluentValidation validators with dependency injection and register them in Program.cs. This setup automatically validates API inputs and command objects as they enter the pipeline.

Yes, implementing FluentValidation for InputModel validation requires a project structure that includes an Application or Validators folder. You also need to add the FluentValidation dependency and register the validators in your Program.cs file to enable automatic validation across use cases.

The best way to enforce validation rules for command objects is to build dedicated FluentValidation validators that check structural correctness and constraints like required fields and length formats. This ensures data integrity by validating inputs before any business rules are executed.

You should use FluentValidation for use case validation when you need to enforce structural correctness on API inputs and command objects before domain logic. It provides a structured approach to manage common rules like required, length, and format across a Clean Architecture setup.
