Most likely cause: Possibly missing handler mapping. By default, the static file handler will handle everything. The feature you want to use might not be installed yet. The corresponding MIME mapping is not enabled for the website or application. (Warning: Do not create MIME mappings for things like .ASPX pages or .config files that users should not download.) If ASP.NET is not installed.
