I hesitate to mention it, because this library has been deprecated but
not yet completely removed:

In it you will find an example of how one might go about reconnecting to
a broker. Be warned that this code will be removed soon and is not
guaranteed to work with recent versions of the broker.

It is not possible to maintain the previous subscription to the broker
and somehow inject a new channel and/or connection into it. You will
need to re-establish all contained channels and all associated
subscriptions when the connection shuts down.

Yes.

When I run your Consumer.exe  standalone I also get the same exception
as before.
