I need to do something like this:
<appSettings>
<add key="Three" value="NumberThree"/>
</appSettings>
<appSettings configSource="One.config"/>
<appSettings configSource="Two.config"/>
This gives me an error: Sections must only appear once per config file.
That kinda sucks :( Just wondering: Is there any way/setting I can enable to do something like this? (IIS7, .net 3.5SP1)
I have very little control of the web.config and can't modify the existing appSettings element, only add new items.
Configurations have a set inheritance hierarchy.
Checkout ASP.NET Configuration File Hierarchy and Inheritance .
EDIT: Another one: How to: Configure Specific Directories Using Location Settings .
Not sure if this will help for you particular scenario. Have a look at the file
attribute on <appSettings>
<appSettings file="Two.config">
...
</appSettings>
In Two.config
you can then do the same to point to One.config
