You need to add the Telerik.OpenAccess.Web assembly as a reference to your project in order to used the Web Datasource. However this control is indeed out-of-date and above all based on OQL. At the moment we are working on a new datasource control that will be much more capable than the existing one as it will be LINQ based. The Visual Studio integration will also be much smoother than the existing one. You can expect the new control in the upcoming Q3 release.
