error while trying to run project: Unable to start debugging on the web server.
The server does not support debugging of ASP.NEt or ATL Server applications.
Run setup to install the Visual Studio server components. If setup has been run
verify that a valid URL has been specified.

You may also want to refer to the ASP.NEt and ATL Server debugging topics in
the online documentation. Would you like to disable future attempts to debug
ASP.Net pages for this project?
