ConnectNamedPipe and asio overlappped ptr
Found the issue. I've not associated pipe with IOCP itself in server part. It can be done by wrapping pipe native handle returned by CreateNamedPipeA into boost::asio::windows::stream_handle just before calling ConnectNamedPipe.
typedef boost::asio::windows::stream_handle StreamHandler;std::shared_ptr<StreamHandler> streamHandler = std::make_shared<StreamHandler>(*mIoService);streamHandle->assign(pipe);
