[ASP.net教程]EF架构~Cannot attach the file as database


回到目录

Cannot attach the file as database这个异常是在EF的code frist里经常出现的,解决方法很简单,只要重新启动一下V11实例即可。

   CMD> sqllocaldb.exe stop v11.0  LocalDB instance "v11.0" stopped.  CMD>   CMD> sqllocaldb.exe delete v11.0  LocalDB instance "v11.0" deleted.  CMD> sqllocaldb.exe start v11.0  LocalDB instance "v11.0" started.

再次运行应用程序,搞定!
