实体框架上下文为静态 [英] Entity framework context as static

问题描述

在Web应用程序中，如果我将实体框架模型的上下文声明为静态，那将会很好吗？会没事的它不推荐？为什么？
谢谢！

解决方案

几乎绝对不会。

随着更多对象的查询/保存，ObjectContext越来越大。

同样在线程之间共享一个ObjectContext，就像您所做的一样，不推荐使用，因为锁定问题和不确定性的副作用您将不得不处理。 / p>

我写了一个关于这个话题的提示。

In a web application it would be ok if i declare the context of a entity framework model as static? it would be ok? its not recommended? why? Thanks!

解决方案

Almost definitely not.

ObjectContexts get bigger and bigger as more Objects are queried / saved.

Also sharing an ObjectContext between threads, as you would be doing, is not recommended, because of the locking issues and undeterministic side-effects you would have to deal with.

I wrote a tip on this topic a while back.
