Records are specialized reference types in C# designed to hold immutable data. They simplify code and enhance safety by reducing boilerplate and providing automatic value-based equality.
Immutability: Records are immutable, which means once created, their data cannot be changed. This enhances thread safety.
Performance: Records have a tiny performance overhead compared to classes due to generated equality methods and value-based comparisons. However, the overhead is usually negligible.
Developer Productivity: Using records can significantly reduce the amount of code needed, making development faster and more efficient.
Perfect Use Cases: Records are ideal for Data Transfer Objects (DTOs), API responses, domain events, configuration objects, and any immutable data structures.
DTOs and API contracts
Configuration objects
Domain events
Value objects
Any immutable data structures
Objects that need frequent updates
Deep inheritance hierarchies
Large mutable collections
Complex business logic
Records = Immutable data containers
Classes = Mutable objects with behavior
By focusing on when and why to use records, you can leverage their advantages to create safer, cleaner, and more efficient C# applications.
