I publish a application in sbdirecorty via VisualStudio Light Switch. The application start, but show this message: Operazione Load non riuscita per la query 'GetAuthenticationInfo'. Errore del server remoto: NotFound. I read several articles on how to publish lightswitch one but I don't understand this step: Eleventh, if you are deploying a XtraReport with you Lightswitch application you need to remember to also FTP over the dll's for DevExpress. This will prevent the "GetAuthenticationInfo" error; which drove me nuts for a week. The dll's go to the "bin" directory on the server. I think this is the problem but I need help ti solve tihs one. thank fulvio
