I have installed IIS 8.5 on Windows 8.1. And I have add my framework 4.0 application in IIS from PORT 81. Framework 4.0 is already with windows 8.1. So I have run localhost:81/Home.aspx it shows an error like as follows
HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.
How to solve this.
