Question

当我将[Remote()]属性添加到类属性时，抛出以下异常：

TypeLoadException：无法从程序集“ System.Web，版本= 4.0.0.0，区域性=中性，PublicKeyToken = b03f5f7f11d50a3a”中加载类型“ System.Web.Routing.RouteValueDictionary”

using System;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;

namespace Entities
{
    [Serializable]
    public class EmployeeEntity
    {
        public int Id { get; set; }
        
        [Required(ErrorMessage = "Required")]
        [MaxLength(20)]
        [RegularExpression(@"^\S*$", ErrorMessage = "No white space allowed")]
        [Remote("IsUserNameAvailable", "Employee",HttpMethod ="GET", ErrorMessage = "EmailId already exists in database.")]

已解决-安装Microsoft.AspNetCoreCore.Routing之后。问题是在ASP核心项目中使用System.Web.Mvc

将远程属性添加到asp.net核心时出错
