Debugging a WCF service on Windows 7 and IIS 7

Debugging a WCF service on Windows 7 and IIS 7

I created and deployed a WCF service, created with Microsoft Visual Studio 2008, to IIS 7 on Windows 7 and I got the error message:
Unable to start debugging on the web server. Could not start ASP .NET debugging. More Information may be available by starting the project without debugging.


So I did, I started the WCF service without debugging an got the error page:
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.

Then I followed the instruction on
, that cleared the error!

  • Run Visual Studio 2008 Command Prompt as “Administrator”.
  • Navigate to C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation.
  • Run this command servicemodelreg –i

    Installed IIS 7 after installing Visual Studio 2008 and .NET Framework 3.5
