This is a beginner's guide to NHibernate that starts from ground zero. Successive chapters build upon earlier concepts, while the sample code presents various ways to accomplish typical data access tasks. Within a few chapters you have a running application using NHibernate to retrieve and store data. We examine all of the topics required to get a functional data access layer implemented by writing the least amount of code possible, presenting options along the way to handle particular edge cases or situations as they arise. When you have completed the various exercises you will have running data-bound desktop and web applications, as well as an understanding of how to implement NHibernate in your own applications. This book is for new and seasoned developers of .NET web or desktop applications who want a better way to access database data. It is a basic introduction to NHibernate, with enough information to get a solid foundation in using NHibernate. Some advanced concepts are presented where appropriate to enhance functionality or in situations where they are commonly used.
