In an ASP.NET web project, you can override web.config appSettings using a
user.config file. Very handy with multiple developers working on the same
project.. I tried doing a similar thing in a Windows form application but
it didn't work. Here's what I tried:

1. Win Forms app.config file had this syntax:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings file="user.config">
<add key="input" value="From the app.config file."/>
</appSettings>
</configuration>

2. I added user.config to base diretory of project, and excluded it from the
project. It's syntax is below:

<appSettings>
<add key="input" value="From the user.config file."/>
</appSettings>

Suggestions?

implies that this is very possible.

Thanks in advance.
