entity-framework - 升级到 EF6 后 - 该属性无法配置为导航属性

Question

我有以下类(class):

[Table("TagSource")]
public class TagSource
{
    public TagSource()
    {
        this.DataSources = new HashSet<DataSource>();
    }

    [Key]
    public int TagSourceId { get; set; }
    ...
    public bool IsHistorical { get; set; }
    public Nullable<int> ModifiedEntryId { get; set; }
    ...
    public int? AttachedTagSourceId { get; set; }        

    [ForeignKey("AttachedTagSourceId"), InverseProperty("TagSourceId")]
    public virtual TagSource AttachedTagSource { get; set; }

    [ForeignKey("ModifiedEntryId"), InverseProperty("TagSourceId")]
    public virtual TagSource ModifiedEntry { get; set; }
}

我使用的是 Entity Framework 5，但现在我已经(通过使用 nuget)升级到最新版本 - 6，之后我遇到了一个错误:

"The property 'TagSourceId' cannot be configured as a navigation property. The property must be a valid entity type and the property should have a non-abstract getter and setter. For collection properties the type must implement ICollection where T is a valid entity type.","ExceptionType":"System.InvalidOperationException"

我已阅读该主题，但我没有描述的引用资料: EF5 to EF6 upgrade - navigation properties are broken

我遇到了同样的问题。我删除了 InverseProperty 属性，问题就解决了。希望对您有所帮助。
