LINQ到NHibernate，讓關鍵字

Question

這是可能的使用let關鍵字與nhibernate linq？ 我寫

var posts = from post in postsRepository.GetPosts(name) 
      let commentsCount = (from c in NHUnitOfWork.CurrentSession.Linq<Comment>() 
            where c.Post.ID == post.ID 
            select c).Count() 
      select new ... 

，並響應我有

NHibernate.QueryException：無法解析屬性：帖子：Sys.Domain.Entities.Post
