attempted to read or write protected memory ASP.Net

I get this error whenever I attempt to run a web app from the IDE. I am using VS 2008 Team Edition, .Net Framework 3.5, SP1. This literally occurs on a brand new app with no code it in it at all. Just a default page. I开发者_StackOverflow hit the run button, and I get the error message. There is no break point, I don't get any error information, just the dialog box.

Click Debug, Exceptions, tell it to break on everything, then try again and give us more detail.

are you running it in the webdev server that visual studio uses automatically or have you set it up to use IIS? If IIS, what version is it?
