升级到 EF6 后 - 该属性无法配置为导航属性 [英] After upgrade to EF6 - The property cannot be configured as a navigation property

问题描述

我有以下课程:

[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:

I was using Entity Framework 5, but now I have upraged (by using nuget) to newest version - 6, after doing that I'm encountering an error:

属性 'TagSourceId' 不能配置为导航属性.该属性必须是有效的实体类型，并且该属性应具有非抽象的 getter 和 setter.对于集合属性，该类型必须实现 ICollection，其中 T 是有效的实体类型.","ExceptionType":"System.InvalidOperationException"

"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，但我没有像描述的那样参考:EF5 到 EF6 升级 - 导航属性已损坏

I have read that topic, but i have no references like described: EF5 to EF6 upgrade - navigation properties are broken

推荐答案

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

I had the same problem. I removed InverseProperty attributes and the problem solved. Hope it helps.
