Why Parallel Code Loses Updates: lock, Interlocked, and Thread-Local State, Measured
Concurrency advice is usually delivered as rules: "use lock ", "prefer Interlocked ", "avoid shared state". Rules are easier to remember when you have watched them fail. So I built a deliberately small experiment, incrementing one counter 100,000 times with Parallel.For , and measured what happens w
