我要寻找最好的ORM工具为我即将到来的.NET Web项目。我所遇到的一级开发和MS实体模型框架的一些选择。没有人指导我哪一个是最好的？实体框架模型，似乎与参照完整性约束问题（级联删除）。哪一个会是更好的选择？

我们一直在使用NHibernate pretty的成功自己。有一个学习曲线有，但我认为这将是预期的东西你怎么做。然而，有人在那里工作，所以我发现很多支持一个庞大的社区。

I am looking for the best ORM tool for my upcoming .net web project. I have come across Tier Developer and MS Entity Model framework as the some of the choices. Does anyone guide me which one would be the best? Entity Framework model seems to have issues with referential integrity constraints (cascade delete). Which one would be a better option?

We have been using nHibernate pretty successfully ourselves. There is a learning curve there but I think that is going to be expected for anything you do. There is however a large community of people out there working on it so I find plenty of support.
