If you try and access the WCF data services using http://SP2010SERVERNAME/_vti_bin/listdata.svc you get the following error message
You need to install an update for the .NET Framework 3.5 SP1. Download from Microsoft here. I found an IISRESET was not enough to get this to work. A full reboot cleared the fault.
