Answer 1

I Found where are my error

the is tried to query two repository

didn't know each repository has his own db context my error was that :

from football in  repoFootabll.Query().Where (x => x.id = 12)
From members in repoMember.Query().where(x=> x.FootaballId = football.id)
select (repo2)

To fix that i just add dbset of football in Member repository

class repoMember 
{
    dbSet<football> foot
    dbSet<member> memeber
 ...
}

and create the function inisde my repo member :

{
     from football in  foot.Where (x => x.id = 12)
    From members in memeber.where(x=> x.FootaballId = football.id)
    select (members)
}
