1. Naming

Basic★ Must knowLesson 1 of 12
  • Names reveal intent: daysSinceLastLogin, not d or data2.
  • Classes = nouns (InvoiceCalculator); methods = verbs (CalculateTotal, SendReminder).
  • Booleans read as questions: isActive, hasAccess, canRetry.
  • Avoid noise words: Manager, Processor, Data, Info (unless they really mean something).
  • .NET conventions: PascalCase for types, methods, properties, constants; camelCase for locals and parameters; _camelCase for private fields; I prefix for interfaces; Async suffix for async methods.
