嗨，我试图运行我的MVC 3应用程序，该应用程序运行SQLCE 4 Embedded和EF4.1
( p& }& h: t8 w+ o$ C我已经使用了本教程中描述的数据访问方法
3 b# D! V3 H3 |9 M这在本地完美地工作（显然），但是在我的主机上运行它时，出现以下错误消息。这是一个共享的托管环境。
0 l1 v# q& r, J# }( u5 `6 d* I0 Z4 H问题是开放的连接吗？它是否应该由工作单元类处理，该工作单元类按教程中所述在整个应用程序中以单例形式返回dbcontext？
6 o$ a5 {8 x8 N" g; w2 J关于这可能由什么引起的任何提示将不胜感激
