Action Steps
  1. Create a record type in C# using the 'record' keyword to define an immutable class
  2. Use the 'init' keyword to define init-only properties in a record type
  3. Apply value equality to record types using the '==' operator to compare instances
  4. Utilize 'with' expressions to create new instances of record types with modified properties
  5. Test record types for immutability and value equality to ensure correct behavior
