c# - LINQ to NHibernate 和 let 关键字

Question

是否可以在 nhibernate linq 中使用 let 关键字？ 我写了

 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 ...

作为回应我有

NHibernate.QueryException: could not resolve property: post of: Sys.Domain.Entities.Post
