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.
SOLUTION:
Ensure you have configured IIS to serve ASP.NET pages with a .SVC extension. To solve this problem
1. On the server with IIS installed start a command window as an Administrator.
2. Go to the 'C:\Windows\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\' directory, or 'C:\Windows\Microsoft.Net\Framework64\v3.0\Windows Communication Foundation\' if using a 64bit operating system.
3. Run this command 'ServiceModelReg -i'
4. Retest you can browse to the service help page.
