Question

I have a table AccountSecurity which is a many-to-many table that relates Account entities and Securities. When I write the query below it returns all Securities that satisfy the where clause. However each Security instance in the list no longer has the reference to the AccountSecurity it came from. So when I do list[0].AccountSecurity it is empty. Is there anyway to include that information? I know I can rewrite the query to return AccountSecurities instead and use .Include(“Security”) on that, but I wonder if it can be done another way.

var list = (from acctSec in base.context.AccountSecurities
            where acctSec.AccountId == accountId
            select acctSec.Security).ToList();

UPDATE

Of course if I do two queries the graph gets populated properly, there has to be a way to do this in one shot.

var securities = (from acctSec in base.context.AccountSecurities
            where acctSec.AccountId == accountId
            select acctSec.Security).ToList();

//this query populates the AccountSecurities references within Security instances returned by query above
var xref = (from acctSec in base.context.AccountSecurities
            where acctSec.AccountId == accountId
            select acctSec).ToList();

var list = (from sec in base.context.Securities
                                    .Include("AccountSecurity")
            where sec.AccountSecurities.Any(as => as.AccountId == accountId)
            select sec).ToList();
