Do you avoid using magic string when referencing property/variable names

(if customer.Address.ZipCode == null) throw new ArgumentNullException("ZipCode");

❌ Figure: Bad Example - Hardcoding a reference to a property

(if customer.Address.ZipCode == null) throw new ArgumentNullException(nameof(customer.Address.ZipCode));

✅ Figure: Good Example - Using nameof() operator to avoid hardcoded strings
