Refactoring legacy C# code involves adopting modern patterns like records for immutable data, init-only properties, and pattern matching to improve readability, testability, and performance for I/O-bound operations and data manipulation.

The best way to enforce immutability in C# 12 is by using records and init-only properties. This approach ensures robust, immutable data structures, reducing side effects and potential bugs in your codebase.

Achieving zero-allocation performance in C# requires using Span<T> and Memory<T> alongside advanced async/await patterns. These techniques minimize memory overhead and optimize data manipulation operations.

Modern C# coding standards fully support nullable reference types to promote robust type safety. Combining them with value objects helps enforce strict data contracts and significantly reduces runtime null reference exceptions.

Use pattern matching in C# to write highly readable, functional-style code for complex data structures. It simplifies conditional logic and type checks, making your codebase more maintainable and easier to test.

Designing high-performance APIs in C# involves applying modern API design patterns, leveraging async/await for I/O-bound operations, and utilizing zero-allocation techniques like Span<T> to optimize data processing throughput.
