I've updated EF from ver 1.0.1 to ver 1.1.0 and after runnig below query I got error.

var data = await _context.CustomerServices
                .Include(a => a.ServiceEquipment)
                .Include(a => a.ServiceAddresses)
                .ThenInclude(a => a.Address)
                .SingleOrDefaultAsync(a => a.Id == serviceId && !a.IsDeleted && !a.ServiceEquipment.IsDeleted);

the binary operator Equal is not defined for the types 'System.Nullable`1[System.Boolean]' and 'System.Boolean'.

when I remove !a.ServiceEquipment.IsDeleted from query it works.
