问题 I have a fairly long-running process (several minutes) that I need to run roughly once a month - but not on a fixed schedule, but after a user clicks Go in a ASP.NET Webforms GUI page. Since ASP.NET really isn't designed to handle long-running background tasks, my idea was to put this into a separate console app. But how to launch that as needed? What happens if I use Process.Start(....) from my ASP.NET page's code-behind? I would like to avoid blocking the whole Web UI for 20 minutes or so..

In the ListView items I have

问题 Whenever I add this line to my web.config in the system.webServer section: <serverRuntime /> With our without properties, IIS 7.5 just serves up a blank page instead of the website.

问题 One web site is required to be accessed by me (developer) and one user (DOMAIN_NAME\USER_NAME). When I developed web site in visual studio using "automatic host" created by VS, the following settings in web.config were enough: <authentication mode="Windows"/> <authorization> <allow users="DOMAIN_NAME\my_name,DOMAIN_NAME\USER_NAME" /> <deny users="*" /> </authorization> But when I created web site in IIS I'm receiving error: Access is denied.
