NHibernate 3.0 Cookbook

By: Jason Dentler

Overview of this book

<p>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.<br /><br />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.<br /><br />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 &amp; 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.</p>

Using NHibernate with TransactionScope


Reliable integration with other systems is a common business requirement. When these systems report error conditions, it's necessary to roll back not only the local database work, but perhaps the work of multiple transactional resources. In this recipe, I'll show you how to use Microsoft's TransactionScope and NHibernate to achieve this goal.

Getting ready

Create a new console application project.

Add references to the Eg.Core project in Chapter 1, NHibernate.dll, and NHibernate.ByteCode.Castle.dll.

Get the console application ready by following the Configuring NHibernate with App.config and Configuring log4net recipes in Chapter 2.

How to do it...

  1. Add a reference to System.Transaction.

  2. Add a public interface named IReceiveProductUpdates with the following three methods:

    void Add(Product product);
    void Update(Product product);
    void Remove(Product product);
  3. Add a public class named WarehouseFacade with this code:

    public class WarehouseFacade : IReceiveProductUpdates...
