如何使用属性避免EF4.4设计中的循环引用？

Question

我有三个表： PropertyOwner ，财产和地址。

PropertyOwner 有很多属性。

PropertyOwner 有一个地址。

每个属性也有地址。

以下是Entity Framework 4.4的代码：

Table: PropertyOwner

[Key]
[DatabaseGenerated(DatabaseGeneratedOption.None)]
[Required]
public Guid PropertyOwnerId { get; set; }

[Required]
[ForeignKey("Address")]
public Guid AddressId { get; set; }
public virtual Address Address { get; set; }


Table: Property

[Key]
[DatabaseGenerated(DatabaseGeneratedOption.None)]
[Required]
public Guid PropertyId { get; set; }

[Required]
[ForeignKey("PropertyOwner")]
public Guid PropertyOwnerId { get; set; }
public virtual PropertyOwner PropertyOwner { get; set; }

[Required]
[ForeignKey("Address")]
public Guid AddressId { get; set; }
public virtual Address Address { get; set; }


Table: Address

[Key]
[DatabaseGenerated(DatabaseGeneratedOption.None)]
[Required]
public Guid AddressId { get; set; }

[Required]
[StringLength(64)]
public string AddressLine1 { get; set; }

当我尝试创建此数据库时，出现以下错误：

The referential relationship will result in a cyclical reference that is not allowed. [ Constraint name = FK_dbo.PropertyOwner_dbo.Address_AddressId ]

数据库是否认为 Property 的地址和 PropertyOwner 的地址是相同的记录？

如何在 Property 需要拥有自己的地址的属性中拼写出来， PropertyOwner 也需要拥有自己的地址

感谢。
