DateTime数据注释在ASP.NET Core RC2应用程序中不起作用

视图模型

public class EditReleaseViewModel : BaseViewModel
{
        [Display(Name = "ReleaseDate",ResourceType = typeof(SharedResource))]
        [DisplayFormat(ApplyFormatInEditMode = true,DataFormatString = "{0:dd.MM.yyyy HH:mm}")]
        [Required(ErrorMessageResourceName = "FieldRequired",ErrorMessageResourceType = typeof(SharedResource))]
        public DateTime ReleaseDate { get; set; }
}

控制器非常简单,如果我删除数据注释并使用默认一切正常.

调节器

[HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<IActionResult> Edit(EditReleaseViewModel viewModel)
        {
            if (ModelState.IsValid)
            {
                ...
            }
        }

视图

<div class="form-group col-sm-12 col-md-6 col-lg-4">
            <label asp-for="ReleaseDate" class="col-md-3 control-label"></label>
            <div class="col-md-9">
                <input asp-for="ReleaseDate" class="form-control" />
                <span asp-validation-for="ReleaseDate" class="text-danger" />
            </div>
        </div>

它是一个ASP.NET核心MVC RC2应用程序 – 也许我在那里缺少一些东西.
