I need help implementing recursion in a general way

I feel like you're gonna have a hard time getting good responses with the way you've phrased this question. What exactly do you need help with? Got examples of something you're having a hard time translating into a recursive function?

✅ Seeding question

one thing to note, though, if you are creating a new entity and it references other entities that already exist, you may only need to set the ID on your join entity

public class OptionMachine {
  [ForeignKey("Machine")]
  public int MachineId { get; set; } = default;
  public Machine? Machine { get; set; } # nullable because you can load the junction entity without loading the nav props

  [ForeignKey("Option")]
  public int OptionId { get; set; } = default;
  public Option? Option { get; set; }

  [Required]
  public decimal Price { get; set; } = default;
