IDisposable SqlCommand

I noticed that SqlCommand implements IDisposable (or rather DbCommand does and SqlCommand inherits from DbCommand), but in some instances in the docs I've seen SqlCommand is not wrapped in a using statement. Is there a reason for this? Maybe we are trusting SqlConnection to garbage collect the resources of SqlCommand?

Is it not a problem if SqlCommand isn't wrapped in a using? It seems I always see SqlConnection wrapped in a using; however, so I assume that's quite important.

Thanks.
