- TargetFrameworks net48;net40. net48 keeps x64 + ViGEm + System.IO.Ports package; net40 adds Microsoft.Bcl.Async + System.ValueTuple and uses the in-box SerialPort. - Compat/TaskCompat bridges Task.Run/Delay/WhenAny/WhenAll (TaskEx on net40) and SemaphoreSlim.WaitAsync (net40 blocks briefly - trivial at 9600 baud). - IReadOnlyList/IReadOnlyDictionary -> IList/IDictionary throughout (net40 predates the IReadOnly* interfaces and the Bcl backport cannot make arrays implement them). - HashCode.Combine replaced with a manual combine (Bcl.HashCode has no net40 build); Marshal.SizeOf<T> -> typeof form; ViGEmJoystickSink gated #if !NET40. HidFeederJoystickSink stays on both flavors - it will drive RioGamepadXP.sys on XP via the same contract. Both TFMs build; 275 tests green on net48.
