C＃console app与DB first Entity Framework和AutoMapper，无法将Model转换为DbModel

Question

我试图让一个基本的控制台应用程序工作，以便我可以使用DB First Entity Framework和AutoMapper将用户输入的数据保存到现有数据库，但是当我尝试将我的本地模型保存回数据库时我无法编译，因为它无法转换db模型的本地模型。

EF生成了以下类：

//------------------------------------------------------------------------------
// <auto-generated>
//     This code was generated from a template.
//
//     Manual changes to this file may cause unexpected behavior in your application.
//     Manual changes to this file will be overwritten if the code is regenerated.
// </auto-generated>
//------------------------------------------------------------------------------

namespace DbModels
{
    using System;
    using System.Collections.Generic;

    public partial class contact
    {
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
        public contact()
        {
            this.address = new HashSet<address>();
        }

        public System.Guid id { get; set; }
        public string full_name { get; set; }
        public string email { get; set; }
        public string mobile_phone { get; set; }
        public System.DateTime created_timestamp { get; set; }
        public System.DateTime modified_time_stamp { get; set; }

        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<address> address { get; set; }
    }
}

然后我有一个当地的contact模型：

using System;
namespace AppModels
{
    public class contact
    {
        public contact()
        {
            id = new Guid();
            created_timestamp = DateTime.Now;
            modified_time_stamp = DateTime.Now;
        }
        public Guid id { get; }
        public string full_name { get; set; }
        public string email { get; set; }
        public string mobile_phone { get; set; }
        public DateTime created_timestamp { get; }
        public DateTime modified_time_stamp { get; }

    }
}

在我的控制台应用程序中，我使用AutoMapper在模型之间创建地图，获取一些用户输入，并尝试将该输入保存到数据库中：

static void Main(string[] args)
{
    var config = new MapperConfiguration(cfg => {
        cfg.CreateMap<DbModels.contact, AppModels.contact>().ReverseMap();
    });

    IMapper mapper = config.CreateMapper();
    var source = new DbModels.contact();
    var dest = mapper.Map<DbModels.contact, AppModels.contact>(source);

    AppModels.contact ContactDetails = new AppModels.contact();
    Console.WriteLine("Enter your name:");
    ContactDetails.full_name = Console.ReadLine();

    Console.WriteLine("Enter your email:");
    ContactDetails.email = Console.ReadLine();

    Console.WriteLine("Enter your phone number:");
    ContactDetails.mobile_phone = Console.ReadLine();

    using (var dbcontext = new myDbContext())
    {
        dbcontext.contact.Add(mapper.Map<DbModels.contact,AppModels.contact>(ContactDetails)); // Argument 1: cannot convert from 'AppModels.contact' to 'DbModels.contact' 
        dbcontext.SaveChanges();
    }



}

dbcontext.contact.Add(ContactDetails);行在编译Argument 1: cannot convert from 'AppModels.contact' to 'DbModels.contact'时抛出错误我在Web应用程序中使用了几乎相同的automapper / EF代码并且一切正常，似乎AutoMapper并没有告诉EntityFramework它可以使用的模型映射。
