Alright I am assuming, based on the error message you provided, that you are woring with chapter 28. (The error specifically said: 'c:\ProCsharp\Chapter28\PCSWebClient1') Problem is, I can not recreate your problem *IF* I follow the readme files.
For example, if i try to directly open the .sln file from the Archive Visual Studio barks that: "...the project file or web has been moved, renamed or is not on this computer."
Now, if i got into my C drive and create a folder named ProCSharp and then inside of that folder create a folder named Chapter28 and then copy all of the example directories to the C:\ProCSharp\Chapter28 location, this corrects the problem.
So your directory tree for C:\ProCSharp\Chapter28 looks like this:
-PCSDemoSite2
-PCSWebClient1
-PCSWebClient2
-PCSWebService1
-PCSWebService2
-PCSWebService3
I tested this in Full blown Visual Studio 2005, 2008 Beta 2, and Visual Web Developer 2005. Can you provide me with any other information?
