This evening I deployed a Silverlight application to my local machine while trying to debug a security / authorization issue. I setup a quick web application in IIS7 on a fairly fresh new version of Windows 7. When I opened the page for the service I was presented with the following.
I went in and looked at the MIME types in IIS7 and sure enough, there wasn’t a .svc MIME type. If you, dear reader, just installed Windows 7 (or Vista) and run into this same issue here is the fix. It is easy. Go to the following path and run the following utility on a command prompt as an administrator (very important!).
c:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\servicemodelreg -i
When you run the command you’ll see this and that is a good thing. After it completes try to reload your page. At least *that* error will be taken care of.
