I\'ve got a DBQuery which converts to an IQueryable (this bit works fine). But then I\'m trying to convert the IQueryable to an O
DbQuery contains Include method so you don't need to convert to ObjectQuery. ObjectQuery is not accessible from DbQuery instance - it is wrapped in internal type InternalQuery and conversion operator is not defined.
Btw. when you add using System.Data.Entity and refrence CTP5 you will be able to call Include on IQueryable!
