What's the most productive way to do NHibernate mapping?

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?

+2  A: 

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.

+1 Have to go fluent to keep POCOs clean and to avoid nasty XML problems when objects are altered.

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

Here's an article that might help you decide.

I apreciate your post. Thanks for the article. I dont't mind attributes in my model, but I don't want every entity to inherit a base class out of the ActiveRecord framework. And I dont't want my entities to take care of their own storage. Like a DAO better ;)

Inheriting from ActiveRecordBase<T> is entirely optional. As a DAO you can use ActiveRecordMediator or a wrapper like Ayende's IRepository: http://github.com/ayende/rhino-tools/blob/master/commons/Rhino.Commons.ActiveRecord/Repositories/ARRepository.cs
