Today, I’m presenting this session from PDC at a local code camp. In setting up my demo, I’ve been trying to get the SharePoint 2010 beta 1 server setup so that it can be queried using WCF Data Services (formerly ADO.Net Data services). Whatever I try, I continue getting the following error:
WebHost failed to process a request.
Sender Information: System.ServiceModel.Activation.HostedHttpRequestAsyncResult/40906347
Exception: System.ServiceModel.ServiceActivationException: The service '/_vti_bin/listdata.svc' cannot be activated due to an exception during compilation. The exception message is: Could not load file or assembly 'Microsoft.Data.Services, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified..
The good news is that there is a solution for this problem. The ADO.Net Data Services 1.5 CTP 2 runtime needs to be installed as well as a patch.
The runtime can be found at: http://www.microsoft.com/downloads/details.aspx?FamilyID=a71060eb-454e-4475-81a6-e9552b1034fc&displaylang=en#filelist
