实体框架（CTP5、Fluent API）。重命名导航属性的列

Question

我有两个实体：

public class Address
{
        public int Id { get; set; }
 public string FirstName { get; set; 
 public string LastName { get; set; }
}

public partial class Customer
    {
        public int Id { get; set; }
        public string Email { get; set; }
        public string Username { get; set; }

        public virtual Address BillingAddress { get; set; }
        public virtual Address ShippingAddress { get; set; }
    }

以下是映射类：

public partial class AddressMap : EntityTypeConfiguration<Address>
    {
        public AddressMap()
        {
            this.ToTable("Addresses");
            this.HasKey(a => a.Id);
        }
    }
public partial class CustomerMap : EntityTypeConfiguration<Customer>
    {
        public CustomerMap()
        {
            this.ToTable("Customer");
            this.HasKey(c => c.Id);

            this.HasOptional<Address>(c => c.BillingAddress);
            this.HasOptional<Address>(c => c.ShippingAddress);
        }
    }

生成数据库时，我的“客户”表有两列用于“BillingAddress”和“ShippingAddress”属性。他们的名字是“AddressId”和“AddressId1”。 问题：如何将它们重命名为“BillingAddressId”和“ShippingAddressId”？

基本上，您希望在独立关联中自定义 FK 列名称，此代码将为您执行此操作：

public CustomerMap()
{
    this.ToTable("Customer");            

    this.HasOptional<Address>(c => c.BillingAddress)
        .WithMany()
        .IsIndependent().Map(m => 
        {
            m.MapKey(a => a.Id, "BillingAddressId");                    
        });

    this.HasOptional<Address>(c => c.ShippingAddress)
        .WithMany()
        .IsIndependent().Map(m =>
        {
            m.MapKey(a => a.Id, "ShippingAddressId");
        });            
}
