is there proceed organisation query linqtosql organization scalar value?

i have those maps repository.

public iqueryable<awtype> getawtypes()
{
    relapse awt _db.awtypes
           name new awtype
           {
               id = awt.id,
               header = awt.header,
               outline = awt.description
           };
}

public iqueryable<aw> getaws()
{
    relapse aw _db.aws
           name new aw
           {
               id = aw.id,
               bw = (from bw getbws()
                          where bw.id == aw.bw
                             name bw
                         ).singleordefault(),
               awtype = (from awt getawtypes()
                            where awt.id == awawtype
                            name awt
                        ).singleordefault(),
               awattribute = aw.awattribute
           };
}

in use i wish count bws grouped awtype list<keyvaluepair<awtype, int>>.
when i linq query :

var awgroups = aw _repository.getaws()
group aw aw.awtype newgroup
select newgroup;

list<keyvaluepair<awtype, int>> retgroups = new list<keyvaluepair<awtype, int>>();
foreach (var organisation awgroups)
{
    retgroups.add(new keyvaluepair<awtype, int>(group.key, group.count()));
}
return retgroups;

i an blunder observant i can't organisation an vigilant i have organisation scalar value aw.awtype.id.

is there proceed "awtype, int" pairs call?
