NHibernate is a mature, 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. NHibernate allows you to use plain SQL and stored procedures less and keep focus on your application logic instead. Learning the best practices for a NHibernate-based application will help you avoid problems and ensure that your project is a success.
The book will take you from the absolute basics of NHibernate through to its most advanced features, showing you how to take full advantage of each concept to quickly create amazing database applications. You will learn several techniques for each of the four core NHibernate tasks—configuration, mapping, session and 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 by the end of the book.
You will also 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 features, you will learn creative ways to extend the NHibernate core, as well as gaining techniques to work with the NHibernate search, shards, spatial, envers, and validation projects.

Chapter 1. The Configuration and Schema
In this chapter, we will cover the following recipes:
Introduction
NHibernate is a popular, mature, open source Object-Relational Mapper (ORM) based on Java's Hibernate project. ORMs, such as LINQ to SQL, Entity Framework, and NHibernate, translate between the database's relational model of tables, columns, and keys to the application's object model of classes and properties.
The NHibernate homepage, http://nhibernate.info, contains blog posts, the complete reference documentation, and a bug tracker. Support is available through the very active nhusers Google group at http://groups.google.com/group/nhusers. The NHibernate source code is hosted on GitHub at http://github.com/nhibernate/nhibernate-core. Precompiled binaries of NHibernate releases are also available on SourceForge and through NuGet at http://nuget.org/packages/NHibernate.
NHibernate provides an incredible number of configuration options and settings. The recipes in this chapter demonstrate several methods for configuring NHibernate and generating the necessary database schema.
Installing NHibernate
Before we begin, let's get our Visual Studio solution and database set up. The following information will get you up and started with NHibernate.
Getting ready
How to do it...
There's more…
Instead of using the graphical package manager, you can use the Package Manager Console. It provides a faster way to install or update NuGet packages. To open the Package Manager Console simply click Tools | NuGet Package Manager | Package Manager Console. In the opened window you can simply write the following:
This will produce the same effect as the main recipe.
Scripting the database
It's usually not appropriate for your application to recreate database tables each time it runs. In this recipe, we'll generate a SQL script to create your database objects.
Getting ready
Complete the Configuring NHibernate with App.config or Web.config recipe at the beginning of this chapter.
Note
This recipe works for any RDBMS supported by NHibernate. To use a different system, adjust your connection string and dialect accordingly.
