Paul Andrew has just announced that the SharePoint Disposable Object checking tool SPDisposeCheck has been released into the wild. Jump over to: http://blogs.msdn.com/pandrew/archive/2009/01/29/spdisposecheck-v1-3-1-is-released.aspx and have a read.
If you are a developer and don’t know about the issues related to disposable objects in SharePoint then have a read of Roger Lamb’s blog post on the topic.
Cheers!
