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# z" }- P3 O- H' T% d u6 M9 Y
我已经使用了本教程中描述的数据访问方法, K( y8 d) z9 c( x' }# k; d& 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。/ \* G/ z8 d* \* T6 o1 | h( W# p
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？
1 O q9 B# z J C; K关于这可能由什么引起的任何提示将不胜感激
