You can create a list from db.Resource and use LINQ to Collections to erase this limitation:

var list = db.Resource.ToList().Select(res => Tuple.Create(res.Resource_ID, res.Name));

The Tuple class does have some constructors (up to 8 items), but the Create() helper method makes the creation more straightforward.
