It appears that, on enabling social rating against my list for my custom content type, I now have 2 extra fields for each
SPListItem in my list:
AverageRating and RatingCount (as explained Blog Link)
So I can access these directly just like I am any other fields. Or, according to MSDN, I can use the SocialRatingManager:
SocialRating aRating = mySocialRatingManager.GetRating(myUri);
When wanting to retrieve the rating for a list item - should I not just take the field value? Or must I use the method referred to by MSDN?
