Overview of this book

NHibernate is an innovative, flexible, scalable, and feature-complete open source project for data access. Although it sounds like an easy task to build and maintain database applications, it can be challenging to get beyond the basics and develop applications that meet your needs perfectly. The NHibernate Cookbook explains each feature of NHibernate 3.0 in detail through example recipes that you can quickly apply to your applications. Set yourself free from stored procedures and inline SQL. Quite simply, if you build .NET applications that use databases, this book is for you. The book will take you from the absolute basics of NHibernate through its most advanced features and beyond, showing you how to take full advantage of each concept to quickly create amazing database applications. Beginners will learn several techniques for each of the 4 core NHibernate tasks – mapping, configuration, session & transaction management, and querying – and which techniques fit best with various types of applications. In short, you will be able to build an application using NHibernate. Intermediate level readers will learn how to best implement enterprise application architecture patterns using NHibernate, leading to clean, easy-to-understand code, and increased productivity. In addition to new v3.0 features, advanced readers will learn creative ways to extend NHibernate core, as well as techniques using the NHibernate search, shards, spatial, and validation projects.

Using dependency injection with entities

In this recipe, I'll show you how we can inject services into our entities to separate implementation details from our real business logic.

Getting ready

Download uNHAddIns.CommonServiceLocatorAdapters.dll from the Unofficial NHibernate AddIns project at http://code.google.com/p/unhaddins/.

Download Ninject.dll and CommonServiceLocator.NinjectAdapter.dll from the Ninject project at http://ninject.org.

Download Microsoft.Practices.ServiceLocation.dll from the Microsoft Patterns and Practices team available at http://commonservicelocator.codeplex.com/.

Put these three assemblies in your solution's Lib folder.

How to do it...

Create a new console application project named IoCByteCode.
Add a reference to NHibernate.dll, NHibernate.ByteCode.Castle.dll, Ninject.dll, CommonServiceLocator.NinjectAdapter.dll, uNHAddIns.CommonServiceLocatorAdapters.dll, and Microsoft.Practices.ServiceLocation.dll.
Add an interface named IPasswordHasher with the following method definition...
