…ThreadId, drop ThreadStart ceremony, join the worker threads - AsynchronousProgramming and Tests retargeted net6.0 -> net10.0 - Test SDK 16.11.0 -> 17.14.1, MSTest 2.2.7 -> 3.10.4 - Thread.CurrentThread.ManagedThreadId -> Environment.CurrentManagedThreadId in all six demo methods - new Thread(new ThreadStart(M)) -> new Thread(M) - ExecuteMultithreading() now joins t1/t2/t3 so the demo output no longer races process shutdown
