SqlServerValueGenerationStrategy 不存在

Question

我什至以为下载了 Microsoft.EntityFrameworkCore.SqlServer 版本 3.1.15 仍然 keepinig

The name 'SqlServerValueGenerationStrategy' does not exist in the current context   ATSActionMonitoringSystem   D:\USERS\ERENT\Desktop\ATSSapanca2022\ATSActionMonitoringSystem\Migrations210928071457_MigrationAddKategoryDeptID.Designer.cs    23  N/A

已经尝试过：

安装包Microsoft.EntityFrameworkCore.SqlServer

它看起来像是安装并定义了我的 .csproj 文件。

你有什么想法可以帮助吗？
