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
: g, Z" S' G. H8 L) C* X我已经使用了本教程中描述的数据访问方法# e% h4 f( m( v7 u
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。# O x5 E! y8 b, ]) G! Y2 v* W$ ^ D0 c
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？8 L" I* l" P: s8 M+ ^3 D
关于这可能由什么引起的任何提示将不胜感激
