C# Values and Value Types
summary
Compares classes, structs, records and record structs by showing concrete code: equals/getHashCode overrides, IEquatable, operator overloads, and the compiler-generated implementations for positional records; demonstrates non-destructive mutation with with-expressions and shows when the compiler’s defaults fail by building Color and Temperature examples that include unit-aware factory methods and validation. Flags surprising pitfalls like default initialization, mutable record-struct defaults, virtual clone costs, and when a handwritten class/struct remains the better choice.
