我下载了一个 AdentureWorks2019.bak,并在 SQL Server Management Studio 中恢复了它。当我尝试使用以下命令在 Visual Studio 2019 中构建基架时:
Scaffold-DbContext 'Data Source=(localdb)\MSSQLLocalDB;Initial Catalog=AdventureWorks;Trusted Connection=True;' Microsoft.EntityFrameworkCore.SqlServer
我收到以下警告:
To protect potentially sensitive information in your connection string, you should move it out of source code. You can avoid scaffolding the connection string by using the Name= syntax to read it from configuration - see https://go.microsoft.com/fwlink/?linkid=2131148. For more guidance on storing connection strings, see http://go.microsoft.com/fwlink/?LinkId=723263.
然后出现如下错误:
PM> Scaffold-DbContext 'Data Source=(localdb)\MSSQLLocalDB;Initial Catalog=AdventureWorks;Trusted Connection=True;' Microsoft.EntityFrameworkCore.SqlServer
Build started...
Build succeeded.

我曾尝试寻找解决方案,但没有成功。如果有人能提供帮助,我将不胜感激!
