Fix HTTP 404.3 web service error after installing VSeWSS 1.3

I have encountered weird web service 404 error after I installed and configured the March CTP of VSeWSS 1.3. I call it weird, because I was expecting access denied error, but not the dreaded "File Not Found" billboard on my way to use the latest version of VSeWSS. :)

Some people have the same problem, too.

Anyway,  given the fact that I was setting up the development environment on a fresh installation of Windows 2008 Web Server I figured out that  the problem is caused by the fact that IIS does not know how to handle the request addressed to the service. So here is the solution:

Win+R > cmd

cd "%SystemRoot%\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\"
ServiceModelReg.exe -i

Enjoy!
