Hi all,
We suddenly received this exception on all solutions on our development server. Apparently noone did anything to provoke it, but now we're attempting to fix it.
Server Error in '/' Application.
An entry with the same key already exists.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Apparently there are duplicate values in cultures, so removing the additional key would probably fix if. But do any of you know how to fix that on the server?
Btw. I reviewed the code for the CultureList in Reflector, and IMHO there's some potential for improvements here;-) Not that that is an excuse for our server setup:)
BR.
