I'm attempting to write a WCF service in VS 2010 which will use the SPSite and other classes to add the users into the SPGroup.
When I run this service it gives me an error "Microsoft SharePoint is not supported with version 4.0.30319.1 of the Microsoft .Net Runtime." I hace already the target framework as .Net 3.5.
Please provide me the solution of this scenario.
Thanks and Regards
