EF add-migration generates empty migration

Question

I added into my model a new table:

public DbSet<ReturnedTransactions> ReturnedTransactions { get; set; }

And i want my migrations to generate that table for me, so i did:

PM> Add-migration returnedTransactions

And it generated

public partial class returnedTransactions : DbMigration
{
    public override void Up()
    {
    }

    public override void Down()
    {
    }
}

How do i force this thing to generate proper code for me?

Answer 1

I see this happen when I do not add my DBSet Entity to my DbContext class that is associated with the Migration Configuration file.

Although, it may not be the case here as we can see that the Asker included the line:

public DbSet<ReturnedTransactions> ReturnedTransactions { get; set; }

Still, this is something one should check when they are returned an empty migration class.

Answer 2

Clear out the _MigrationHistory table.
