Description

when I send data with Guid.Empty, the validator success validation instead of fail validation.

Reproduction Steps

using System.ComponentModel.DataAnnotations;
using Microsoft.AspNetCore.Mvc;

namespace WebApplication2.Controllers;
[ApiController]
[Route("[controller]")]
public class FooController : ControllerBase
{
    [HttpPost]
    public FooModel Foo([FromBody] FooModel fooModel)
    {
        return fooModel;
    }
}

public class FooModel
{
    [Required(AllowEmptyStrings = false, DisallowAllDefaultValues = true)]
    public Guid? Id { get; set; }
}

Expected behavior

{
  "type": "https://tools.ietf.org/html/rfc9110#section-15.5.1",
  "title": "One or more validation errors occurred.",
  "status": 400,
  "errors": {
    "Id": [
      "The Id field is required."
    ]
  },
  "traceId": "00-b7dcd87be3c66cde040e34fc685d4c7a-6a1eb125481c8a9f-00"
}

Actual behavior

{
  "id": "00000000-0000-0000-0000-000000000000"
}
