Description
Latest error message on LiveView issue with 8.0.0 TIMOB-25072 shows that we might need to gracefully close TCP connection just before application exit - sample code: https://gist.github.com/infosia/a4d617b6678a5efef445eb7301b8b4c2#file-liveview-diff-L54 I think this has never happened on iOS/Android/WindowsPhone because application lifetime is totally controlled by each frameworks...but it seems things are different for Windows Store app because user can explicitly kill the app manually by pressing Window's [x] button. I don't know why this has never happened on previous versions but maybe we need to handle this natively, like explicitly closes all open-connection gracefully just before application exit.
*Steps to reproduce*
appc run -p windows -l trace --target ws-local --liveview -l trace and then exit the app by pressing [x] button on the title bar
*Result*
[INFO] Disconnected from app
-- End application log -------------------------------------------------------
