Make hard coding your default choice

To my experiences, I divide this kind of  "magic number" into three categories:

#1 Very small chance to change: Hard coding
#2 Good chance to change in the future:
  Hard coding with default value but checking config file first
string ConfigSetting_SMTP_host = ConfigurationManager.AppSettings["SMTP_host"] ?? "";

#3 For sure change (such as dev vs product environment): read from config file directly
