我有一个我在VS 2017中创建的数据库项目。我已经大大改变了它，包括将列移动到不同的表等。
然后我删除了bin＆obj文件夹。我还去了C：\ Users \ david \ AppData \ Local \ Microsoft \ Microsoft SQL Server Local DB \ Instances \ ProjectsV13，在正在运行的进程中杀死了sqlserver.exe，然后删除了该文件夹中的所有文件。
我建立时仍然会得到以下内容：

为什么不开心？
谢谢 - 戴夫
我想通了。打开SSMS并连接到（LocalDb）\ ProjectsV13（将ProjectsV13替换为您的数据库的名称）。在我的情况下，数据库位于C：\ Users \ david \ AppData \ Local \ Microsoft \ Microsoft SQL Server Local DB \ Instances \ ProjectsV13，名称来自该文件夹。
打开后，选择SSMS中的DB并将其删除。一旦你知道该怎么做，真的很简单。
BTW - 连接到localhost不会提供本地数据库。只是（localdb）不起作用。
