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
! C' w. s3 r8 Z4 p3 K' @我已经使用了本教程中描述的数据访问方法9 X0 M o' ]. W. m9 [6 I& B o' Y1 R
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 K, _$ F0 r$ E3 P1 k- `$ A# {
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 s% K( s$ s) m9 Z" i
关于这可能由什么引起的任何提示将不胜感激. d% ^, R# k, `6 p: p. `
