ASP.NET 中的迁移核心代码首先不起作用

Question

I used to be able to do migrations using this command我曾经能够使用此命令进行迁移

dotnet ef migrations add seedData  -p Persistence/ -s API/

But now I get an error:但现在我得到一个错误：

I have looked online and I tried updating the dotnet-ef tool:我在网上查看并尝试更新dotnet-ef工具：

dotnet tool update --global dotnet-ef

Successfully updated
Tool 'dotnet-ef' was successfully updated from version '3.1.3' to version '3.1.6'.

I reference these packages in my project:我在我的项目中引用了这些包：

Microsoft.EntityFrameworkCore.SqlServer
Microsoft.EntityFrameworkCore.Design
Microsoft.EntityFrameworkCore.Tools

Can anyone suggest to me why my migrations are working anymore.任何人都可以向我建议为什么我的迁移工作了。 Thanks谢谢
