All,
Mark Bailey has reported a versioning problem with the Web.config files for Chapter 1's \WROX\ADONET\Chapter01\CS\LINQforBinding and \WROX\ADONET\Chapter01\
VB\LINQforBinding projects.
The attached LINQforBinding.zip file has fixes to the Web.config and LINQforBinding.sln files, which also appear to have a minor problem.
My thanks to Mark for reporting the problem and apologies for the problems.
