Comparing Records, Structs, and Classes in C#: When to Use What?

C# offers three main type declarations: classes, structs, and records. Classes are reference types that support object-oriented principles and are ideal for complex data objects. Structs are value types meant for simple, lightweight data structures with no inheritance, making them efficient for value-based comparisons. Records, introduced in C# 9.0, combine features of both classes and structs; they are immutable reference types and provide concise syntax for type declarations. Each type serves distinct scenarios and optimizes specific use-cases.
