At Step 7 the build fails with error Error 1 Could not load type 'System.Data.Entity.Design.AspNet.EntityDesignerBu ildProvider'. C:\BegASPNET\Source\Chapter 15\web.config 22
Even your own source code fails.

Please advise.

Hi there,

When did you download the source? A few days ago, a new version was uploaded that should fix the problem with the downloadable code.

How did you create this web site and the model? The problem is that some setting are missing from web.config; however they should have been added by Visual Web Developer when you added the ADO.NOT model.

Which exact version of Visual Studio are you using? The RTM version? (Check Help | About for details.)
