LINQ到NHibernate，让关键字

Question

这是可能的使用let关键字与nhibernate linq？ 我写

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 ... 

，并响应我有

NHibernate.QueryException：无法解析属性：帖子：Sys.Domain.Entities.Post
