Learning NHibernate

Question

I am interested in learning NHibernate.

So, I found this: http://www.summerofnhibernate.com/

I would like to watch these, but I am afraid that the videos are for a previous version of NHibernate. Is this true and if so should I still watch them? Is there a current video series?

Any other suggestions for learning NHibernate?

Answer 1

You should still watch them, they are great, and almost all of it still applies.

Some great articles:

• Your very first NHibernate application – Part 1
• Your very first NHibernate application – Part 2
• Your very first NHibernate application – Part 3
• Introduction to NHibernate (7 parts)

A great blog about NHibernate:

• NHibernate FAQ

If you don't like XML mapping, you should also take a look at Fluent NHibernate:

• Homepage
• Wiki

Answer 2

I'm in a similar position, there are a few videos on DimeCasts that you might find useful:-

Ian Cooper also has some blog entries that might be relevant

Answer 3

I would suggest that you grab a copy of the excellent book NHibernate in Action

Although it covers NHibernate 1.2 it's very good at explaining the OR/M fundamentals of NHibernate and some general design principles for using NH in applications.

Buying it with the pdf version on the side will give you a nice searchable reference.

Answer 4

You'll find a lot links on Delicious.com and also NHForge hasn't been mentioned yet

Answer 5

There is a fairly good article about NHibernate Best Practices by Billy McCafferty- The Author of S#arp Architecture - that is a must read if your getting into NHibernate.

Also, I would HIGHLY recommend watching the Summer of NHibernate. It is really well done and still VERY applicable.

Answer 6

I also enjoyed NHibernate Best Practices.

Answer 7

Learning NHibernate is a kind of "twice" process:

1. The first step it's to learn the concepts (and this are similar between versions)
2. The second step it's to learn the peculiarities of the current version

So, the great sources are:

• The NHibernate FAQ
• NHForge
• NHibernate KNol
• Summer of NHibernate
• The Ayende Blog's NHibernate category
• The Fabio Maulo Blog

The first four links are the places where it's possible to learn all the basics and more about, but the last two blog's link are of the two guys of the NHibernate development team and I think, these are the better place to learn.
