FYI, this can be written in a lot less lines:
using (IntelliCloudContext context = new IntelliCloudContext())
{
return context.Feedbacks
.Include("Answer")
.Include("Question")
.Include("User")
.Where(f => f.Answer.Id == answerId)
.ToList()
.Select(f => ConvertEntities.FeedbackEntityToFeedback(f));
}
