    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }
}

迁移工作正常。我创建了迁移并在SQL Server中创建了数据库。现在，当我尝试创建迁移时，我收到此错误。

dotnet-ef : The term 'dotnet-ef' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, 
verify that the path is correct and try again.

我在互联网上尝试了一些解决方案，但仍然收到错误。我错过了任何套餐吗？

Answer 1

通过Powershell而不是Package Manager控制台运行dotnet-ef。或者，在Package Manager Console中将当前目录更改为项目目录（使用cd。

另外，请确保已安装Entity Framework Tools包
