How to Fix a Common SharePoint 2010 OData Error
May 4, 2011
According to Microsoft, OData “… applies web technologies such as HTTP, Atom Publishing Protocol (AtomPub) and JSON to provide access to information from a variety of applications, services, and stores.”.
Recently I was working with OData for a Fpweb.net SharePoint Server 2010 hosting client, and encountered the following error:
"Could not load type 'System.Data.Services.Providers.IDataServiceUpdateProvider' from assembly 'System.Data.Services, Version=126.96.36.199, Culture=neutral, PublicKeyToken=b77a5c561934e089'."
So what the heck does that mean?!?!
This error indicates that there is a missing assembly (
System.Data.Services) on the SharePoint 2010 Web server which is required for processing the OData requests from ListData.svc.
How can I fix this SharePoint Ninja-Style?!?!
Good question, grasshoppa… To remedy this error you will need to install the ADO.Net Data Services Update for .NET Framework 3.5 SP1 (x64).
Important Notes About Installing the Update:
- Notice that there are different versions for different operating systems.
- Be aware that the installer will ask you to reboot after the installation completes.
How do I know if I fixed the OData Error?
