C# 尝试定义1:1关系时出现多重性无效错误

所以我有一个场景（在ASP.NETMVC中）要求我有四个表。其中三个表需要与第一个表具有1:1的关系。当我尝试运行code first迁移来定义这一点时，会出现以下错误：

One or more validation errors were detected during model generation:

ANA_ANASection2_Target: : Multiplicity is not valid in Role 'ANA_ANASection2_Target' in relationship 'ANA_ANASection2'. Because the Dependent Role properties are not the key properties, the upper bound of the multiplicity of the Dependent Role must be '*'.
ANA_ANASection3_Target: : Multiplicity is not valid in Role 'ANA_ANASection3_Target' in relationship 'ANA_ANASection3'. Because the Dependent Role properties are not the key properties, the upper bound of the multiplicity of the Dependent Role must be '*'.
ANA_ANASection4_Target: : Multiplicity is not valid in Role 'ANA_ANASection4_Target' in relationship 'ANA_ANASection4'. Because the Dependent Role properties are not the key properties, the upper bound of the multiplicity of the Dependent Role must be '*'.

如何正确激活这些关系？我不介意丢失数据，因为我们仍在开发中

我的模式如下（我将尝试简化它）：

您只需要在ANA中将字段标记为虚拟字段。除此之外，您使用的是3个相同的类，为什么不在表中添加一个节ID并将其减少为1？我已经极大地简化了类，它们实际上都有与问题无关的非常不同的字段。试图将其标记为虚拟，但不起作用。

public class ANASection2
{
    [Key]
    public int ANASection2Id { get; set; }
    [ForeignKey("ANA")]
    public int ANAId { get; set; }
    [Required]
    public virtual ANA ANA { get; set; }
}

public class ANASection3
{
    [Key]
    public int ANASection3Id { get; set; }
    [ForeignKey("ANA")]
    public int ANAId { get; set; }
    [Required]
    public virtual ANA ANA { get; set; }
}

public class ANASection4
{
    [Key]
    public int ANASection4Id { get; set; }
    [ForeignKey("ANA")]
    public int ANAId { get; set; }
    [Required]
    public virtual ANA ANA { get; set; }
}

public class ANA
{
    public int ANAId { get; set; }
    [Required]
    public ANASection2 ANASection2 { get; set; }
    [Required]
    public ANASection3 ANASection3 { get; set; }
    [Required]
    public ANASection4 ANASection4 { get; set; }
}
