How to Write High-Performance C# Code
— Writing code that runs quickly is sometimes at odds with writing code quickly. C.A.R. Hoare, computer science luminary and discoverer of the QuickSort algorithm, famously proclaimed, 'Premature optimization is the root of all evil.' The extreme programming design principle of 'You Aren't Gonna Need It' (YAGNI) argues against implementing any features, including performance optimizations, until they're needed.
