This zip contains sample code for Wrox Professional Enterprise .NET. Chapters 1, 2 and 9 do not have any source code files. It's important to note that the code works with the current versions of libraries at the time of publishing. So if you update any of the libraries to a newer version, make sure you check for compatability issues and breaking changes - for example in the NHibernate and NUnit examples. Please discuss the code in the forum on the Wrox site - http://p2p.wrox.com/book-professional-enterprise-net-523/ and we will try and answer any questions as soon as we can. There is also a CodePlex project for the final chapter complete solution located here - http://proent.codeplex.com/. Have fun and enjoy the book Jon Arking Scott Millett http://www.linkedin.com/in/ScottMillett http://www.elbandit.co.uk
