Question

实体框架的严重问题＆amp; sql server 2008，请帮忙!! 系统在本地运行良好，但在生产服务器的负载测试期间，我们有超过10个用户的跟随错误。

收到此错误后，用户无法再登录。

'/'应用程序中的服务器错误。执行该命令需要一个开放且可用的连接。连接的当前状态已被破坏。

这是SQL Server日志

看看这个类似问题的答案是否可以帮到你：

EF recovery from invalidoperationexception caused by server being down

或者这个：

Answer 2

您如何存储ObjectContext？从EF的角度来看，您必须确保每个用户都获得对ObjectContext的唯一引用。为此，我通过将它存储在HttpContext.Current.Items集合中来共享ObjectContext。有关Items集合的更多信息，请参阅此处：http://abhijitjana.net/2011/01/14/when-we-can-use-httpcontext-current-items-to-stores-data-in-asp-net/
