I have a web forms app that calls a WCF service. This is a long running service, sometimes 30 minutes, that runs synchronously. When I call the web service, a modal UpdateProgress popup displays, and should display until the process completes. This popup
just shows the user that the process is still running. Everything works perfect when I run the app in Debug mode. When I run the app in Release mode, the modal popup disappears a few minutes into the web service call, but the web service continues to run
as normal. Any ideas what might be causing the modal popup to disappear when in Release mode? Is there maybe some sort of page timeout that I'm missing?
Thanks
