Question

i am doing some research about entity data model in asp.net and there is one make me confused.
e.g.

var tombstoneQuery = from t in crnnsupContext.Tombstones
                                                 from p in crnnsupContext.ProvStates
                                                  where t.RegNumber == _username && t.Province_State == p.ProvinceStateID
                                                  select t;

what i want to do is push all the retrieved result into the cache when user login, so it just connect database once.

so i insert tombtoneQuery into Cache. the problem is how i can get the data from the tombstoneQuery, as I know it is a IQueryable object right? so is there a way to execute it?

I have saw someone done this

ObjectResult<Contact> results = (from c in context.Contacts
                             select c).Execute();

but it poped up an error said IQueryable does not contain a definition for Execute()
anyone can help. much thanks

If you want to execute the query and materialize the results, it sounds like you really want:

List<TombStone> results = tombstoneQuery.ToList();

… and then put that in your cache.
