在实体框架中更换自我跟踪实体6 [英] Replacement of Self-tracking entities in Entity Framework 6

问题描述

我确信大多数.NET开发人员必须以这种方式面对这个问题。问题很简单，我将项目从 .NET 4升级到.NET 4.5.1 。到目前为止这么好，升级完美。但是当我从EF4升级到EF6时，我的查询中遇到很多错误。其中一些与重命名我所做的上下文有关，但对于与自我跟踪实体相关的错误，我有点困惑。

自我跟踪实体是我的项目的主要部分，EF6不支持他们意味着我必须重写我的 DAL 的主要部分。我试图找出，但是在EF6中却没有找到STE的替代方案。

有没有人知道这种情况？我必须重写我的STE依赖的查询。答案不应该包括解释为什么微软决定把STE放在后面，因为我已经经历了许多博客解释说。

解决方案

有一个开源项目叫做可追溯实体，为EF6.0中的STE提供支持

这是一个 blog post 将可跟踪实体与STE进行比较。

I am sure most of .NET developers must be facing this issue one way or the other. The problem is simple, I am upgrading my project from .NET 4 to .NET 4.5.1. So far so good the upgrade went neatly. But when I upgraded from EF4 to EF6, I did encounter lot of bugs in my queries. Some of these were related to renaming the context which I did, but as for the errors related to Self-tracking entities, I am a little confused.

Self-tracking entities are a major part of my project and EF6 not supporting them means I will have to rewrite a major part of my DAL. I tried to find out but have not been able to find any alternative to STE in EF6.

Does anyone know way around to this scenario? Will I have to rewrite my STE dependent Queries. The answers should not include explanations on why Microsoft decided to put STEs behind as I have already gone through many blogs explaining that.

解决方案

There is an open source project called Trackable Entities that provides support for STEs in EF6.0

Here is a blog post comparing Trackable Entities to STEs.
