Migration

The basic unit of FM is the Migration abstract class. Your migrations will derive from this class and implement two methods. You also need to define the Migration attribute with a unique identifier. Commonly, this identifier is just an incrementing value, although the attribute accepts a Int64, some people use a numbered date format such as yyyyMMdd. The significance of this number is for the ordering of your migrations. Lower numbers execute first and then larger. It also provides a way to target a specific migration. Your migration class that you create is where you define the migrations to execute.

[Migration(1)]
public class CreateUserTable : Migration
{
    public override void Up()
    {
        Create.Table("Users");
    }

    public override void Down()
    {
        Delete.Table("Users");
    }
}
