By default, Entity Framework Core migrations will put your migration code inside of a Migrations folder in the root of your project. This isn't always desirable, but luckily changing the output folder is easy. All you need to do is specify the option
-o followed by the desired path. The example below will output migration code into the Migrations folder located within the Model folder.
Note that you'll only need to specify the output argument for the first migration. Entity Framework Core is smart enough to put future migrations in the correct folder.
