i安装 Visual Studio Enterprise 2017
使用其安装程序，我检查了 Data Storage and processing
和 Sql Server Express 2016 来自单个组件
因此，我可以在C#应用中访问LocalDB，但是当installer/modifer完成时，它会产生错误：
Setup completed with warnings -> Couldn't install sqllocaldb
在我发现的日志文件中：
Package 'sqllocaldb,version=15.1.61710.120,chip=x64,language=en-US' failed to install.
。
The installer has encountered an unexpected error
The error code is 2349. Copy resumed with different info.
