C# 9 introduces records, a new reference type that you can create instead of classes or structs. C# 10 adds record structs so that you can define records as value types. Records are distinct from classes in that record types use value-based equality. Two variables of a record type are equal if the record type definitions are identical, and if for every field, the values in both records are equal. Two variables of a class type are equal if the objects referred to are the same class type and the variables refer to the same object. Value-based equality implies other capabilities you’ll probably want in record types. The compiler generates many of those members when you declare a record instead of a class. The compiler generates those same methods for record struct types.
