升级到EF6后 - 属性不能被配置为导航属性 [英] After upgrade to EF6 - The property cannot be configured as a navigation property

问题描述

我有下面的类：

[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; }
}

我是用实体框架5，但现在我已经upraged（通过使用的NuGet）到最新的版本 - 这样做之后，我遇到错误6：

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'不能被配置为一个导航属性​​，该属性必须是一个有效的实体类型和属性应该有一个非抽象的getter和setter。对于集合属性的类型必须实现的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"

我已阅读的话题，但我有这样描述的引用：
<一href=\"http://stackoverflow.com/questions/21787156/ef5-to-ef6-upgrade-navigation-properties-are-broken\">EF5到EF6升级 - 导航属性被打破

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

推荐答案

我有同样的问题。我删除 InverseProperty 属性和问题解决。希望它帮助。

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