Go to the wrox website and locate your book Beginning....2.0, under download code at the bottom there is entry "Final Application" which is 2.18M or so. That entry is the Wrox United. Also check out the Errata Sheet and Appendix B for setup.
I am still working thru ASP.NET 1.1 and ASP.NET Databases, so I dont have the 2.0.
Hope this helps.
