In case that we have in appsettings;
"settings": {
    "url": "myurl",
    "username": "guest",
    "password": "guest"
  }and we have the class;
public class Settings
    {
        public string Url { get; set; }
        public string Username { get; set; }
        public string Password { get; set; }
    }we can use also;
var settings = builder.Configuration.GetSection("Settings").Get<Settings>();
var url = settings.Url;Reference
