Is there any good books for NHibernate? Or any tutorials or quick guide. I'm getting a hard time with the documentation. It's so technical. I would love reading on explanations and good use of NHibernate objects or something like that... Thanks!

Most of the documentation and samples for Hibernate are relavent to NHibernate. There a couple things NHibernate does not support yet that Hibernate 3 supports. There are some good books for Hibernate, but not specifically for NHibernate.

Have a look at the starter projects with NHibernate source code and also look at some of the code in the test projects to get a feel for how stuff works.

If you are unfamiliar with ORM tools there will be a higher learning curve for getting used working with the API.

My advice, start small, test, add, test, add, ....
For testing I would use NUnit, mainting database state can be pain, but for starting small you should be able to set everything up in Setup and Teardown methods. The tests are an excellant way to play around with NHibernate until you are used to it.

NHibernate is a very powerful tool, every newbie has been in your shoes, don't get too frustrated yet, it takes a little getting used to.

Best of Luck

Ok thanks! I do have Hibernate book (not NHibernate). Just got it from a friend. Better read this when I have time. Pretty much busy on work. Thanks!

So, are there any online tutorials on NHibernate like.... "Query - How to?" or something like "Filter date - How to?". Hehehe. My titles my sound silly but you know what I mean.

There may be NHibernate books in the future, at least that's what I heard from ...

bang

Hey, who are you? NSA!?! What the ...? I didn't do any....

Wait! No, I swear, I don't actually know ...

Just ... Wait! No!

Just let me click ... ow! That hurts! Just a sec ... where are you taking me? What's that needle for? NO!

Seriously, aside the NHibernate documentation, there are many resources available on the internet; most of them are listed in the NHibernate resources page.

If you are just starting with object/relational mapping, there are many tutorials which try to progressively introduce NHibernate, namely the NHibernate Quick Start Guide and NHibernateEg.

Good luck.

It looks like you can now get the NHibernate in Action book. (Currently in MEAP) authored by Pierre Henri Kuaté, Christian Bauer and Gavin King.

Given the author lineup hopefully should be a great read.

Now, people can understand this post ;)

Until NHibernate In Action appears I'd recomment Hibernate In Action.

Not only does a lot of its content apply equally well to NHibernate but I was also impressed that it was actually an enjoyable read and its worth getting it just to get an understanding of some of the theory behind ORM.

How about "Java Persistence with Hibernate"?

"Java persistence with Hibernate" focus on Hibernate 3.0. As there are many changes between Hibernate 2.0 and 3.0 i would prefer "Hibernate in Action" as this book focus on Hibernate 2.0.

NHibernate in Action's first chapters are already accessible through the MEAP and the remaining chapters will be released very quickly.

Look good! So could you tell us briefly what makes your book different than "Hibernate In Action"? Put another way, I already has Hibernate In Action. Why do I need to buy "Nhibernate In Action"? And could you design a more complicated domain model as the sample in the book? That will be very beneficial.

Thanks!

It is more than just a translation of the book, there is new information there specific for .Net.
If you already has Hibernate In Action, of course there is a large degree of overlap between the two books, but that is to be expected, they cover the same subject.

Depending on the version of NH that you use, you may try (at your own risk :D ) http://www.hibernate.org/379.html.

Hope it can be of some help.
