Yay! My first contribution!
I've been having this problem for a few weeks...
I'm working on a migration projet :
- .Net 1.1 -> 4.0
- IIS6 -> IIS7, etc.
The problem was that in a specific case numbers were multiplied by 1000. By setting the site .Net Globalization parameters to "fr-FR" (we're in France) the problem was sold... for a few days. Except the problem came back randomly... or so I thought.
Actually by doing so, IIS created a web.config file at the root of the site and from times to times I was deleting this file, because it shouldn't be there... Why? Because the application wasn deploying in a separate directory within the site's directory.
The web.confing was saying this :
<?xml version="1.0" encoding="UTF-8"?>
<globalization culture="fr-FR" uiCulture="fr-FR" />
And then all became clear : this should be written in the web.config of the application.
Actually, I'm testing the solution, but it seems to be on the right track.
