I've upgraded a VS 2005 app to VS 2008, and tried to run it. I get some very strange behavior. Something, I don't know what, comes up and says:
"Unable to start debugging on the web server. <!DOCTYPE html PUBLIC "-//W3C/DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd <html xmlns="http://www.w3.org/1999/xhtml">; <head>; <title>;IIS 7.5 Detail Error - 500.19 - Internal Server Error</title>;
and then it goes on with a lot of HTML. But the weird thing is that this window isn't one I could scroll through, or copy anything out of. (I had to do a screen clip and save it as a .png graphics file, so if I've copied anything wrong, I'm sorry about that.) Anyway, it looks as though it was a part of VS 2008, but there wasn't anything I could do with this window other than close it. What is this error and what can I do about it?
