Question

I am using linq with SQL CE, but for a simple query like this:

var points=from i in this.DomainBoundaryPoints orderby i.Index select i;

I get this error:

Could not find an implementation of the query pattern for source type 'System.Data.Linq.EntitySet<DAL.DomainBoundaryPoint>'.  'OrderBy' not found.  Are you missing a reference to 'System.Core.dll' or a using directive for 'System.Linq'?

Does SQL CE support ‘order by’ TSQL clause? Where is the problem?

Answer 1

Of course SQL CE supports orderby…

Try to do what the error message tells you…

• add a reference to System.Core if it’s not there
• add a using directive for System.Linq
