推荐答案
发现问题!
问题是我的解决方案中的启动项目是建模项目。
由于某些原因,在我的项目中启用迁移时,该模块将查看与启动项目相关的库。
Found the problem!
The issue was that the startup project in my solution was a modeling project.For some reason when enabling migrations on my project, the module looks at libraries related to the startup project.
将我的启动项目更改为测试项目解决方案和一切工作。
Changed my startup project to be a test project in the solution and everything worked.
更新
确保您的启动项目包含要用于连接到数据库的 app.config
或 web.config
文件。即使您的 DbContext
位于不同的项目中,它也将用于生成迁移的文件。您可以将包含您的 DbContext
的项目设置为启动项目。
Make sure your startup project contains the app.config
or web.config
file you want to use to connect to database. This is the file that it will be used to generate migrations even if your DbContext
is located on a different project. You can set the project containing your DbContext
as the startup project.
