It covers moving unit tests to a shared templated test harness, handling the tricky case of collecting all timers during shutdown, and fixing an inconsistency so that both timer classes initiate shutdown properly when wrapped in a thread-safe facade. The code builds with Visual Studio 2022 and 2026, targets Windows 10 by default, and is available on GitHub under the MIT license. ## Full article daily.dev links to this article rather than hosting it.
