Entity Framework Core 3.1 生成迁移文件报错

报错信息：
Your startup project 'EFCore.DomainModels' doesn't reference Microsoft.EntityFrameworkCore.Design. This package is required for the Entity Framework Core Tools to work. Ensure your startup project is correct, install the package, and try again.

报错描述：我即使选择了Data这个项目，它还是安装默认项目处理，因此修改默认项目即可
