What's the most productive way to do NHibernat

Question

I know annotations to do the hibernate mapping in Java and am looking now for a similar way to do the same in C# and NHibernate. I found out that there exists several approaches

• do the mapping in xml files
• NHibernate.Mapping.Attributes (NHMA)
• Fluent
• are there any more??

I tried NHMA and found out it had some blocking points for me...

I don't want you to discuss, whats the best way to map models to NHibernate, but I was looking for a good comparison on the internet.

Do you know such sites? What facts are the main points to consider, if I choose one of the "frameworks" listed above? I'm thinking of aspects like 'is this project offically supported by the NH-Developers?', 'are there models that can be mapped in xml-mapping but not in fluent/NHMA/etc...?'

What can you recommend? Why?

Answer 1

Another option, if you don't mind attributes, is Castle ActiveRecord.

Here's an article that might help you decide.

Answer 2

Fluent NHibnernate auto mapping or code generation (CodeSmith, MyGeneration, T4, etc.) are the most productive ways to create the mapping files. I dislike the attributes approach because I like to keep my POCOs plain.
