In the book the custom exception class AppException inherits from System.ApplicationException. The downloaded code, however, inherits from Exception.

Yes, I am new to .Net and don't understand the difference. Does it matter which I use? The downloaded code built and ran, but I am slowly constructing a new version by following the book.

Book:
public class AppException: System.ApplicationException
Download:
public class AppException: System.Exception

Conventional wisdom used to be that we should always inherit from System.ApplicationException for our own custom exceptions. However, it isn't required, and there's been some talk at Redmond lately about a different point of view - some people prefer inheriting from System.Exception. Read about the controversy here:
