SqlConnection.Dispose - in addition to closing the connection, it also
clears stateful nature of the SqlConnection instance, like connection string
etc.Beneath this layer, in SqlConnection atleast, there is a connection
pooling mechanism, which eventually holds actual physical database
connections. Again, they aren't really unmanaged resources, but non .NET
resources nonetheless. Lest I cause any confusion SqlClient has TDS parsing
built into .NET code, so technically in this scenario - there wasn't any
unmanaged resource.

So in short, Dispose does not **have** to release unmanaged resources - and
by convention it does cleanup. Thats exactly what SqlConnection.Dispse
does - "clean up clean up everybody do your share"
