Through much searching I have been unable to figure out how to order by a ContentItem's Owner. I believe the owner is part of the CommonPart, but I can't quite figure out how to work that into a Linq query.
Here's what I've been working with:
.OrderByDescending<ContentPart>(x => x.ContentItem.CommonPart.Owner.)
This doesn't work of course, but it's along the lines of where I'm trying to go with this.
Any thoughts? I'd appreciate any pointers.
