我正在尝试在我的解决方案之一上安装 EntityFramefork，但 Package Manager Console无法识别 Enable-Migrations .
PM> Enable-Migrations
Enable-Migrations : The term 'Enable-Migrations' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a pa

我也从不同的线程中遵循了这些步骤，但没有成功:
1. 使用 -IncludePrerelease 重新安装 EF
2.以管理员权限重启VS
Package Manager Console Enable-Migrations CommandNotFoundException only in a specific VS project
最佳答案
EF Core 不再具有 Enable-Migrations 命令。 “默认”启用迁移。使用 Add-Migration 添加新迁移。
关于包管理器命令的文档是 here
关于entity-framework - 启用迁移 : The term 'Enable-Migrations' is not recognized as the name of a cmdlet，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44057203/
