我得出的结论是，localdb不是用于生产的SQL Server的受支持版本.

I have come to the conclusion that localdb is not a supported version of SQL Server for production.

如此处所述

LocalDB是SQL Server引擎的一种特殊的，低影响的版本，它不是作为Windows服务安装的，而是由ADO.NET客户端根据需要打开(使其运行)并打开与它的连接.它仅适用于单用户方案，不用于任何产品用途-生产时，应使用SQL Server Express(或更高版本)

LocalDB is a special, low impact version of the SQL Server engine, that is not installed as a Windows Service, but launched (made to run) on demand by the ADO.NET client opening a connection to it. It is intended for single user scenarios, and not for any prodcution use - for production you should use SQL Server Express (or higher)
