On my prioer contract, we used Entity Framework 4.0 and LINQ, at my suggestion and had a tremendous success. My next job uses NHibernate with Fluent as their ORM, also with SQL Server 2008.
I used NHibernate years ago with ActiveRecord and Rhino Igloo, but don't have a lot of recollection on how to use that. I assume Fluent would be much different.
Can I use LINQ and Lamdba expressions with NHibernate?
Are there partial classes where I can add functionality on top of the base functionality of the ORM?
Please give me an idea of what to expect that's different between NHibernate Fluent and Entity Framework 4.0 and LINQ.
