我有一个包含多个项目的解决方案.DBContext文件和Models位于ClassLibrary项目中.这个项目有EF 6.1.3,它运行在.NET 4.5.2上.模型和DBContext文件采用不同的文件结构,我的意思是模型在Project/Data/Model中,而DBContext在Data文件夹中.此项目似乎已启用到现有数据库的迁移.开发团队过去只是通过构建项目来重新创建数据库.它也有:

AutomaticMigrationsEnabled = true;

我正在尝试正确使用迁移,并尝试按照以下方式查看PackageManagerConsole正确反应.

Enable-Migrations
Add-Migration InitialCreate –IgnoreChanges

两者都导致以下错误:
