I was working away just fine on my ASP.NET 2.0 application (Win7 64 bit, IIS 7.5.76) when all of a sudden I get a pesky error message "Unable to start debugging on web server" when I start the app in Visual Studio. The error message (attached) is HTML text and is so long that I can't even get to the bottom of it to see what the punchline is. It happens with debug switched on and off. Any help would be appreciated...
