Hi, I'm trying to re-factor some legacy code that was using businesslogic.Tags to use the new Tag service. I created a TagQuery object using the TagService but this is also deprecated in favour of using the TagService and a PublishedContentQuery object in the constructor.

How can I create a PublishedContentQuery object? Its expecting a ContextualPublishedContentCache object and a ContextualPublishedMediaCache object in its constructor. How do I get these? Thanks
