Just encountered a problem that’s soooo simple to solve, but yet sooo frustrating when you encounter it.
I was moving some code from my local prototype project up to the official dev environment. At first I forgot some entries in the app.config file. Piece of cake, right?
So off to some cut-n-paste action and I ended up with this:
Looks alright? Well it did to me, so imagine my surprise when I got hit with the following exception:
System.Configuration.ConfigurationErrorsException was unhandled
Message="Configuration system failed to initialize"
Source="System.Configuration"
BareMessage="Configuration system failed to initialize"
Line=0
I messed around with it for a while thinking I’d introduced some weird character somewhere or something like that. But no sir, that was not the problem. After googling searching at live.com for a while, I found someone saying that the <configSection> element needs to be the first thing in the config-file.
Perhaps this can save someone else a little time and frustration.
