Currently I think EF only supports to add migrations on projects not yet on class libraries.

And just side note for anybody else who wants to add migrations to specific folder inside your project:

EF CLI not support this yet. I tried --data-dir but it didn't work.

The only thing works is to use Package Manager Console:

1. Pick your default project
2. use -OutputDir command parameter, .e.g., Add-Migration InitConfigurationStore -OutputDir PersistedStores/ConfigurationStore command will output the mgiration to the folder 'PersistedStores/ConfigurationStore' in my project.

public void ConfigureServices(IServiceCollection services)
{
    ...

    string dbConnectionString = services.GetConnectionString("YOUR_PROJECT_CONNECTION");
    string assemblyName = typeof(ProjectDbContext).Namespace;

    services.AddDbContext(options =>
        options.UseSqlServer(dbConnectionString,
            optionsBuilder =>
                optionsBuilder.MigrationsAssembly(assemblyName)
        )
   );

   ...
}
