FYI, in this specific example, because you're using an ADO.net connection and Command object, be aware that the using statement just executes the Command.Dispose, and the Connection.Dispose() which do not actually close the connection, but simply releases it back into the ADO.net Connection pool to be reused by the next connection.open ... which is good, and the absolutely correct thing to do, bc if you don't, the connection will remain unuseable until the garbage collector releases it back to the pool, which might not be until numerous other connection requests, which would otherwise be forced to create new connections even though there's an unused one waiting to be garbage collected.
