Thanks for Bryan's input.
Hi Hk,
As for the projects you're currently dealing with, are they developing upon
..net framework 1.1/ vs2003 or .net framework 2.0/vs 2005. In .net framework
2.0, the new configuration system has provide the support of linking an
external file for individual configuration section in the application
config file (app.config or web.config).
#Managing Changes to Configuration Settings
http://msdn2.microsoft.com/en-us/library/ms228058.aspx #Configuration & ASP.NET 2.0
http://odetocode.com/Blogs/scott/archive/2005/07/04/1906.aspx The above reference has demonstrate its usage in asp.net application.
However, it also applies for most built-in configuration sections (such as
configuration Section under <system.net> , <system.diagnostics> .....).
For example, your main app.config can look like below:
======================
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings configSource="appSettings.config"></appSettings>
<connectionStrings configSource="connectionStrings.config" />
<system.diagnostics
configSource="system.diagnostics.config"></system.diagnostics>
<system.net>
<settings configSource="system.net_settings.config"></settings>
</system.net>
</configuration>
====================
The detailed settings of each section is defined in the external config
file. e.g.
=========appSettings.config==============
<?xml version="1.0" encoding="utf-8" ?>
<appSettings>
<add key="key1" value="value1"/>
<add key="key2" value="value2"/>
</appSettings>
=========================
So far I haven't found any built-in add-in that can help automatically do
this or merging separate files together. We need to do such separate
configuration ourselves.
In addition, if you're using ASP.NET 2.0, there is a add-on project called
"Web Deployment Project". This add-on project can help us do customized web
application precompilation, and one of the feature in it is let us specify
configuration section replacement at the precompile time. You can have a
look at the following article which has demonstrate the configuration
section replacement:

any other questions on this, please feel free to post here.
