C# EF代码首先添加它'；在我定义的FK旁边有自己的FK

我有两个类，从Identity 2.0扩展而来的applicationuser和我自己的对象。我已经定义了我自己的外键，但是当一个db迁移EF添加4个FK而不是2个时

材料清单：

public class MaterialsList
{
    [Key]
    public Guid Guid { get; set; }
    public Customer Client { get; set; }
    public MaterialsListStatus Status { get; set; }
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime Date { get; set; }


    public String CreatedByGuid { get; set; }
    [ForeignKey("CreatedByGuid")]
    public virtual ApplicationUser CreatedBy { get; set; }


    public String AssignedToGuid { get; set; }
    [ForeignKey("AssignedToGuid")]
    public virtual ApplicationUser AssignedTo { get; set; }

    public virtual ICollection<MaterialsRow> Rows { get; set; }
}

---

有没有人有解决这个问题的方法，最好是使用数据注释？只有在没有其他选项的情况下，我才尝试使用Fluent api。

您可以通过在每个列表上添加

InverseProperty

注释来解决此问题，如前所述。本质上，Entity Framework无法自动确定

ApplicationUser

适用于

public class ApplicationUser : IdentityUser
{
    [Required]
    public string FirstName { get; set; }

    [Required]
    public string LastName { get; set; }

    [InverseProperty("CreatedBy")]
    public virtual ICollection<MaterialsList> CreatedMaterialsLists { get; set; }
    [InverseProperty("AssignedTo")]
    public virtual ICollection<MaterialsList> AssignedMaterialsLists { get; set; }
}

公共类应用程序用户：IdentityUser
{
[必需]
公共字符串名{get；set；}
[必需]
公共字符串LastName{get；set；}
[反向属性（“CreatedBy”）]
公共虚拟ICollection CreatedMaterialsLists{get；set；}
[反向财产（“转让给”）]
公共虚拟ICollection AssignedMaterialsLists{get；set；}
}
