How to handle disconnection / reconnection with windows StreamSocket

Question

What is the correct way to handle a disconnection and re-connection event with the windows StreamSocket class (TCP)?

I have an issue where calling "Invalid Operation, method was called at an unexpected time" when calling async_connect after a disconnection event

do I need to create a new streamsocket, or wait for some amount of time before attempting to re-connect?

The solution was to add the following code:

// on catching an exception
socket.dispose();
connect();

// connect function
connect():
    socket = new StreamSocket ...

It was necessary to 1) call socket.dispose() on the socket which the client disconnected from and 2) create a new socket (socket = new StreamSocket(...)). Reusing the same socket to connect did not work.
