If you want automatic paging, sorting, filtering, etc. you can use OData/WCF DataService with RadDataServiceDataSource or WCF RIA Services with RadDomainDataSource. Both services (WCF RIA
and Data) however support official only EF - LINQ to SQL was moved in a toolkit.
With plain WCF services nothing will be automatic - you need to write custom code to handle paging, sorting, etc.
