It is fine that you can access IsolatedStorage upon exit but most of the business scenarios require accessing servers to update database or trigger performing some "logout" tasks, even storing settings remotely not to be bound to local isolated storage on a single machine. Neither WCF nor HTTP calls are allowed and this is one of the troubles LOBs have these days. I really hope this will be fixed for Silverlight 5. http://www.silverlightshow.net/items/Application-Events-in-Silverlight.aspx#comment5988 Denis Vuyka http://www.silverlightshow.net/items/Application-Events-in-Silverlight.aspx Tue, 26 Apr 2011 22:08:10 GMT
