Error when browsing to wcf service .svc

PROBLEM: You try to hit your WCF Service and get an error. When you try to browse to it you get the following error:

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.

SOLUTION: This usually means that WCF is not registered with IIS. You can manually register it by clicking on start and run and running the following command:

C:\windows\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\servicemodelreg.exe -i

If the directory does not exist then it means the proper version of the .net framework is not installed. You can install the proper version from the Microsoft site.

If you have any tips, tricks, or resources, please email them to Susan Fischer at and we will post them.
