Head to Head
summary
Live QA digs into concrete .NET oddities: a Linux .NET Core test run proves 6–10× slower than Windows, traced by isolating a single unit test, using Stopwatch and removing assertions to find a culture-aware string comparison optimization missing on Linux and a CLR fix plus a NUnit workaround is created; other answers show Enum.GetValues + Cast for enum iteration, why try/catch can change speed by ~30% (register vs stack use), and pitfalls of deep cloning with cycles and JSON serialization.
