When I visit my local SP2010 instance on Windows 7 at localhost/_vti_bin/listdata.svc I get Internet Explorer cannot display the webpage. There's no details even though I've turned off Friendly errors in IE9 and have the web.config set as
<customErrors mode="Off" />.
I attempted to create a Console application with VS2010 and add a service reference. I get the following error:
There was an error downloading 'localhost/_vti_bin/listdata.svc'. The operation has timed out Metadata contains a reference that cannot be resolved: 'http://localhost/_vti_bin/listdata.svc'. The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'. The remote server returned an error: (401) Unauthorized. If the service is defined in the current solution, try building the solution and adding the service reference again.
Note: a separate port 16xxx instance works fine. It isn't working on port 80.
