Sharepoint 2010 Visual WebPart and LinqDataSource

Question

How do I use Linq DataSource in a SharePoint 2010 Visual Web-part. When I type <asp:LinqDataSource there are nothing in the Visual Studio auto-complete. When I run the code I would get this error Unknown server tag 'asp:Linq DataSource'

Thanks for your help.
