This New Feature Gives Superpower to C# Record Types

C# 14 introduces extension methods for record types, enabling static factory methods to be attached directly to types rather than separate classes. The guide demonstrates building domain models with records using factory methods for validation, with expressions for non-destructive mutation, extension methods for behavior, and pattern matching with switch expressions. Records reduce code length by 2-3x and significantly decrease bugs through immutability and built-in features.
