I can’t find a dedicated post about it, so I thought I’d draw attention to this thread in the MSDN forums where Michael Washam [MSFT] replied…
Do not dispose properties.Feature.Parent..
However, if you use .ParentWeb or anything else the same rules apply..
Now, the rule for
SPWeb.ParentWeb is that it should not be disposed if you don’t own the child
SPWeb, which we don’t, but you get the idea. It would be great if SPDisposeCheck would catch this—Roger?
