The C# downloads for the samples for the Wrox Press book Beginning ASP.NET 2.0 are provided separately, one per chapter, and a final complete application. This allows each chapter to remain distinct, allowing reworking without destroying a central application. Also, as some chapters include the complete application, separate downloads allows smaller individual downloads.

You should unzip each file into the same folder which will give you the following structure:

            Begin\Chapter01
                 \Chapter02
                 \ChapterNN
            End\Chapter01
               \Chapter02
               \ChapterXX
            WroxUnited
        

The Begin folder is for the working through the chapter exercises, while the End folder is a reference point, containing the code at the end of the chapter.
