I've made short investigation and found this http://stackoverflow.com/questions/16895819/wp8-socket-connectasync-completed-handler-always-returns-success. It's strange because documentation(https://msdn.microsoft.com/ru-ru/library/bb538102(v=vs.110).aspx) says that: If you are using a connection-oriented protocol, the ConnectAsync method starts an asynchronous request for a connection to the remote host, I understood that for tcp ConnectAsync should wait for successful handshake... but anyway I will try advice from stack overflow.
Any ideas about it?
