How to fix ASP.NET error “The file 'nnn.aspx' has not been pre-compiled, and cannot be requested.”?

Question

I have a VS 2005 web site that I publish using \"Publish Web Site\", and I clear all the three checkboxes. I also have a deployment project that picks up the published files

Answer 1

I got this error when I upgraded a site from 2.0 to 4.0. The error was caused by a file PrecompiledApp.config in the site's root directory. Once I deleted that file, the site started working.
