There're some sources files in the book <ASP.NET Website Programming Problem-Design-Solution, Visual Basic.NET Edition>, take the file
AppException.vb for example, its structure is as following:
Imports System
Imports System.Web
Imports System.Diagnostics
Namespace
WebModules
Public Class AppException
Inherits System.Exception
... ... ...
End Class
End Namespace
but in the responding class library
Wrox.WebModules.Core.dll, the namespace
WebModules is replaced by
Wrox.WebModules which has a additional prefix
Wrox, I wonder how the additional prefix
Wrox comes.
