I built a WCF service recently which would run fine in the visual studio test web server, but when i tried to actually hit it from real life IIS7 also on my local box, i receievd 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.
Luckily, i found the solution on David Waddleton’s blog and it was as simple as turning on a windows feature in add remove programs- on my vista box i had to go to Control Panel > Programs and features > Turn on/ off Windows features > Microsoft.NET framework 3.0 and tick the WCF activitation options!
