I absolutely agree, most people have enough problems upgrading as it is, and dont need extra ones ...

My sugegstions is that if your module only needs changes to < appSettings >, then the best thing you can do is to instead create a separate file called "yourmodule.config".  Put all your settings in there and read them using the XmlDocument class.

Using this method allows seamless upgrades without requiring the user to make extra web.config changes.  Your users will thank you for it! :)

Of course if you need to make changes to other sections like < httpModules > etc, then you dont have much choice about changing web.config, and should do all the things mentioned above to make sure that the user knows about the changes and what to do in the event of an upgrade..
