@CESARDELATORRE @RamonTC @eiximenis please, could you give me any feedback?

OK, so you are basically adding the ProducesResponseType attribute, even when sometimes there's a single response type (like "200") but because most methods are returning an IActionResult instead of a direct DTO, right?
And sometimes, because you want to specify additional responses like "NotFound" or "Created", or your actions return IActionResult instead of a response DTO.
I think it looks good. I'm testing the PR and everything seems to work good.
@eiximenis Do you have anything else to add/comment?

Merging. Thanks SychevIgor! 👍
