HTTP Error 404.17 Not Found – Using WCF .SVC Service

So you’re getting IIS error’s when trying to run a .svc file that’s coded to use WCF or Windows Communication Foundation.

HTTP Error 404.17 - Not Found

The requested content appears to be script and will not be served by the static file handler.

or maybe..

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.

Took me awhile to realize I need to setup/configure IIS and WCF properly.  Here are the steps from MS, I went through and realized I had missed one component (IIS6 Scripting tools, who would have thought), which I probably didn’t need, but the big ones that I didn’t have WCF Http Activation installed.  After that, I registered WCF..

"%WINDIR%\Microsoft.Net\Framework\v3.5\WFServicesReg.exe" /c

and then I was golden, but there might be other things you are lacking or missing. So go through all the steps.
