Have you used the record data structure in your projects?

The record data structure in C# is a special type designed for storing immutable data with automatic implementation of comparison and hashing methods.

Example of using a record:

public record Person(string FirstName, string LastName);

var person1 = new Person("Ivan", "Ivanov");
var person2 = new Person("Ivan", "Ivanov");

// person1 and person2 are considered equal because they have the same field values
bool areEqual = person1 == person2; // true

In projects, records are convenient for DTOs, data models where immutability and correct comparison of objects by value, not by reference, are important.
