This application behaves similarly to the Unix ping application, although with fewer options supported.
The application can be used to send ICMP echo requests to unicast IPv4 and IPv6 addresses. The application can produce a verbose output similar to the real application, and can also export statistics via a trace source. The ping packet count, packet size, and interval between pings can be controlled via attributes of this class.

Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.
