FAQ # ...: Why does the Toolkit add resources binaries to a website's bin directory?
To explain the motivation behind this I have put up a wiki on our CodePlex site that details how to make the most of the Localization features without getting overwhelmed by the language resource binaries. We believe that the defaults we have set work best for users who are interested in localizing their websites as well as users who do not need that feature at all. It is now very easy to develop, configure and deploy websites using the Toolkit that are globally aware. We wish to continue adding neat features to the Toolkit and we hope that this feature is serving you well.
