I am trying to Use Core.Settings.LocaleAndLanguage sample when the program starts the first command should be a GET in which case the redirect in Page_PreInit method of default.aspx.cs should work.
Using Core.Settings.LocaleAndLanguage first command seems to be a POST rather than a GET in which case the redirect in Page_PreInit method of default.aspx.cs does not work. (I get an error "An error occurred while processing your request") If I use https I have a certificate problem. Click on ignore it and still get the same problem.
To reproduce this behaviour I Compile and Debug Core.Settings.LocaleAndLanguage sample.
