Since the generated methods create an close the connection for each method call you would assume that it would be possible to call those methods multiple times within a single transaction which obviously isn't the case. As far as I remember, I haven't ever seen a note about that the connection may not be returned to the pool even if you call Close on it. Every discussion on this topic seems to assume that Close is not called properly on the connection thus it's leaked some way or another, but hopefully this thread may be of help to others as well.
