A record in C#, introduced in C# 9.0, is a reference type that provides a concise way to define immutable data structures. Records are designed to make it easier to work with data-centric types, such as those used in data transfer objects (DTOs) or value objects.
Here are the key features of records in C#:
Immutability
Records are immutable by default, meaning that once created, their properties cannot be changed. This helps prevent unintended modifications and promotes thread safety.
Concise Syntax

Equality and Comparison
