I am not sure I understand the question. What files did you download? The ones for the Beginning book or the Professional book? And what is missing exactly?
Planet Wrox is only featured in Beginning
ASP.NET 3.5 / 4 / 4.5 in C# and VB
. However, you posted this question in the forum for the book Professional
ASP.NET 4 in C# and VB
so maybe you just downloaded the wrong files?
