app.config and LUA

If you have a copy, or have access to a copy, take a look at pg416 of "Microsoft Visual C# 2005 Step by Step" (Microsoft Press). The line that gets up my nose is "If the user needs to ..... can edit the configuration file by using a text editor..." arggh!

Considering that this is a .net 2.0 book, and you'd reasonably expect applications written in .net 2.0 to be compliant with LUA when Vista comes along, this is a pretty shonky piece of advice. "Joe User" shouldn't be able to change an app.config file, and shouldn't even want to!
