C# 尝试将EF和Automapper与嵌套DTO一起使用时获取NotSupportedException

我正在使用Automapper，但是我的相关表有问题

这是一个测试模式

CREATE TABLE [dbo].[AddressTable](
    [AddressId] [int] NOT NULL,
    [AddressLine1] [varchar](50) NOT NULL,
    [AddressLine2] [varchar](50) NOT NULL,
 CONSTRAINT [PK_AddressTable] PRIMARY KEY CLUSTERED ([AddressId] ASC)
)

CREATE TABLE [dbo].[FooTable](
    [FooId] [int] NOT NULL,
    [MailingAddressId] [int] NULL,
    [ShippingAddressId] [int] NULL,
 CONSTRAINT [PK_FooTable] PRIMARY KEY CLUSTERED  ([FooId] ASC)
)

ALTER TABLE [dbo].[FooTable] ADD  CONSTRAINT [FK_FooTable_AddressTable_Mailing] FOREIGN KEY([MailingAddressId])
    REFERENCES [dbo].[AddressTable] ([AddressId])
ALTER TABLE [dbo].[FooTable] ADD  CONSTRAINT [FK_FooTable_AddressTable_Shipping] FOREIGN KEY([ShippingAddressId]) 
    REFERENCES [dbo].[AddressTable] ([AddressId])

INSERT INTO [dbo].[AddressTable] VALUES (1,'123 Fake St','Apt 1')
INSERT INTO [dbo].[AddressTable] VALUES (2,'345 Real Ave','')
INSERT INTO [dbo].[FooTable] VALUES (1,1,2)

我使用database first方法生成了一个EDMX文件，然后重命名了

FooTable

中地址的两个相关属性，并删除了

AddressTable

侧的两个属性。这是它生成的EDMX

我知道是

AddressDTO

类的映射导致了这些错误。从

FooDTO

中注释它们可以消除错误

我对导致这种情况发生的相关集合做了什么错事

using System.Linq;
using AutoMapper;
using AutoMapper.QueryableExtensions;


namespace Sandbox_Console
{
    class Program
    {
        class FooDTO
        {
            public int FooId { get; set; }
            public AddressDTO MailingAddress { get; set; }
            public AddressDTO ShippingAddress { get; set; }
        }

        class AddressDTO
        {
            public string AddressLine1 { get; set; }
            public string AddressLine2 { get; set; }
        }

        static void Main()
        {
            Mapper.CreateMap<FooTable, FooDTO>();
            Mapper.CreateMap<AddressTable, AddressDTO>();

            Mapper.AssertConfigurationIsValid();

            using (var ctx = new TestDbEntities())
            {
                var collection = ctx.FooTables.Where(a => a.FooId == 1).Project().To<FooDTO>();

                foreach (var fooDTO in collection)
                {
                    System.Diagnostics.Debugger.Break();
                }
                System.Diagnostics.Debugger.Break();

            }
        }
    }
}
