Diagram showing a record struct value being copied between two variables, illustrating value semantics.

C# record struct: Value Semantics with Record Features

Record structs combine C# value-type semantics with record syntax. See how positional declarations, value equality, mutation, readonly variants, and performance tradeoffs work, and when to choose one over a record class or plain struct.
