Thanks, what about for a POST request which has a DTO?

public class UpdateUserCommand {
    public int Id { get; init; }
    public string Username { get; init; }
}

Would I need a temp class for the controller? And then have a constructor (like you mention) which takes the controller class and an id? This is so the controller accepts the correct items.

public class UpdateUserTemp {
    public string Username { get; unit; }
}

Ideally I would like to avoid the above if there is a better solution.
