We are getting ready to begin redevelopment of a large aging internal enterprise application. We have decided to use ASP.NET MVC, but under consideration is which Object Relational Mapping (ORM) to choose. There are of course a multitude of open source and paid ORM implementations available. However, NHibernate seems to hold the largest mindshare, while the Entity Framework is the new hotness from Microsoft.
While we are doing research and toying around with both we wanted to put it to the community as to which ORM (NHibernate, Entity Framework, or otherwise) they prefer and why.

You should have a look at Sharp Architecture an ASP.NET MVC application framework which uses NHibernate.
I’ve used a few O/RMs in the past couple of years and there’s no way would chose anything other than NHibernate.
I don’t know what more information people will be able to give you over and above in the questions that you have linked to.
