我正在使用localdb进行一些Entity Framework存储库集成单元测试。 我已经实现了标准的构建配置，在读取初始问题之后我应该初始化并启动SQL Local DB。 为此，我添加了以下内容来测试项目后期构建：
"C:\Program Files\Microsoft SQL Server\120\Tools\Binn\SqlLocalDB.exe" create "V12.0" 12.0 -s
但我在本地和Visual Studio Online Build中遇到错误，如：
The sp_configure value 'contained database authentication'
must be set to 1 in order to create a contained database.
You may need to use RECONFIGURE to set the value_in_use.
经过一些研究后，我又添加了以下内容。
sqlcmd -S "(localdb)\V12.0" -Q "EXEC sys.sp_configure N'contained database authentication', N'1';"
sqlcmd -S "(localdb)\V12.0" -Q "RECONFIGURE WITH OVERRIDE;"
这解决了本地问题，但在VSO构建代理中我仍然会遇到错误。看来 localdb 已初始化OK，但 SQLCMD 可以找到刚刚创建的服务器实例。记录下面。
"C:\Program Files\Microsoft SQL Server\120\Tools\Binn\SqlLocalDB.exe" create "V12.0" 12.0 -s
sqlcmd -S "(localdb)\V12.0" -Q "EXEC sys.sp_configure N'contained database authentication', N'1';"
sqlcmd -S "(localdb)\V12.0" -Q "RECONFIGURE WITH OVERRIDE;"
LocalDB instance "V12.0" created with version 12.0.2000.8.
LocalDB instance "V12.0" started.
