实体框架和多线程 [英] Entity Framework and multithreading

问题描述

我有一些处理消息的WCF服务。我用的EntityFramework来检索信息。我添加这些消息到一个线程池队列，然后处理它们。处理所有的消息后，我呼吁实体框架的更新来更新消息的状态。

I have a WCF service that processes some messages. I use EntityFramework to retrieve the messages. I add these messages to a ThreadPool queue and then process them. After processing all the messages, I call an update on the Entity Framework to update the status of the messages.

Durng此操作，笔者随机得到的错误 - 。EntityMemberChanged或EntityComplexMemberChanged被称为无需先调用EntityMemberChanging或EntityComplexMemberChanging在同一个变化跟踪器具有相同的属性名。有关正确报告更改，请参见实体框架文档。

Durng this operation, I randomly get the error - "EntityMemberChanged or EntityComplexMemberChanged was called without first calling EntityMemberChanging or EntityComplexMemberChanging on the same change tracker with the same property name. For information about properly reporting changes, see the Entity Framework documentation."

此错误时抛出ReportPropetyc​​hanged事件特定属性被炒鱿鱼。

This error is thrown when the ReportPropetychanged event for a particular attribute gets fired.

任何帮助将是AP preciated。

Any help would be appreciated.

推荐答案

不共享的ObjectContext - 或连接到它的任何对象 - 线程之间。这是证明是非线程安全的。

Don't share an ObjectContext -- or any object attached to it -- between threads. It is documented to be non-thread-safe.
