Validator.TryValidateObject不调用远程验证

Question

我有一个带有远程验证数据注释的类，如下所示：

public partial class LuInspectionWindow
{
    [Required]
    public int InspectionWindowId { get; set; }

    [Required]
    public string Description { get; set; }

    [Required]
    [DataType(DataType.Date)]
    public DateTime StartDate { get; set; }

    [Required]
    [Remote("ValidateWindowEndDate", "InspectionWindow", AdditionalFields = "StartDate")]
    public DateTime EndDate { get; set; }
}

调用此注释：

[AcceptVerbs("Get", "Post")]
public IActionResult ValidateWindowEndDate(DateTime? endDate, DateTime? startDate)
{
    int minWeeks = 8;

    if (startDate.HasValue && endDate.HasValue
            && (endDate < startDate.Value.AddDays(minWeeks * 7)))
    {
        return Json(data: $"Inspection window end date must be at least {minWeeks} weeks after start date.");
    }

    return Json(data: true);
}

如果我使对象无效，然后按如下方式验证它，我只得到一个错误，对于空描述（标记为Required），根本不检查远程验证。

luInspectionWindow.EndDate = luInspectionWindow.StartDate.AddDays(1);
luInspectionWindow.Description = null;

var context = new ValidationContext(
    luInspectionWindow, serviceProvider: null, items: null);

var results = new List<ValidationResult>();

var isValid = Validator.TryValidateObject(luInspectionWindow, context, results);

await _context.SaveChangesAsync();

远程验证在视图中工作正常，因此它已正确连接。期望Validator.TryValidateObject检查远程验证吗？
