是否有可能使关系修正时更改跟踪被禁止，但生成代理 [英] Is it possible to enable relationship fixup when change tracking is disabled but proxies are generated

问题描述

我有形成树形关系的实体。

I have entities which form a tree relationships.

class MyEntity
{
    public int Id {get;set;}

    public int ParentId {get;set;}
    public virtual MyEntity Parent {get;set;}

    public virtual ICollection<MyEntity> Children {get;set;}
}

在这些实体被称为没有 AsNoTracking（）关系是固定的了。

When these entities are called without AsNoTracking() relationships are fixed up.

var entities = MyEntitiesSet.ToList();

所有的导航属性和集合设置
但是，如果 AsNoTracking（）被称为：

var entities = MyEntitiesSet.AsNoTracking.ToList();

没有导航属性设置。这是可以理解的。但我不明白为什么收集和naviagtion属性不会重写提供关系修正了这个code：

no navigation property is set. This is understandable. But I cannot understand why collection and naviagtion properties are not overriden to provide relationship fixup for this code:

entity.Parent = anotherEntity;

在这里，我想到的是 anotherEntity.Children 集现在包含实体。唉，这是错误的期望，我experimetns显示。

Here I expect that anotherEntity.Children collection now contains entity. Alas, this is false expectation as my experimetns show.

时有可能得到所需的行为不启用更改跟踪？

Is it possible to get desired behavior without enabling change tracking?

我loked在生成的代理，并指出，被覆盖的集合是代理类型的hashsets。 TEntity＆GT; 什么是真实的的 EntityCollection＆LT备份12月22日/ POCO-代理部分-1.aspx相对=nofollow> EF 4 ObjectContext的代理。

I loked at generated proxies and noted that overriden collections are hashsets of the proxy type. They are not backed up by EntityCollection<TEntity> what was true to EF 4 ObjectContext proxies.

和我已经找到了答案<一href="http://connect.microsoft.com/VisualStudio/feedback/details/760609/poco-navigation-proxies-should-fixup-the-other-end-automatically"相对=nofollow>此处。
的DbContext不会产生这些修复了关系代理。

And I've found the answer here.
DbContext does not generate proxies which fix up relationships.

推荐答案

的DbContext的不生成它修复了关系代理。

DbContext does not generate proxies which fix up relationships.

证明是在这里：<一href="http://connect.microsoft.com/VisualStudio/feedback/details/760609/poco-navigation-proxies-should-fixup-the-other-end-automatically" rel="nofollow">http://connect.microsoft.com/VisualStudio/feedback/details/760609/poco-navigation-proxies-should-fixup-the-other-end-automatically

然而，当entitties被附加到上下文加载相关实体：

Yet, when entitties are attached to the context loading related entities:

context.ASet.ToList();
context.BSet.ToList();

自动设置的关系。

sets relationships automatically.
