Question

When I tried to see this service http://win-j8t24f4b519/_vti_bin/listdata.svc

I got this error What should I do?

Was it helpful?

Solution 2

The problem is that I had not installed Ado.net data services!

OTHER TIPS

Another thing to check is to see if the assembly actually is in the GAC (C:\windows\assembly).
