         {
             if (op.IsCompleted)
             {
                 op.Results.FirstOrDefault().PESSOA_PROFISSAO.ForEach(Profissoes.Add);

                 agDataGrid3.DataSource = Profissoes;

Hi Bala;

Could you try and change your query as follows

_em.PESSOA_PROFISSAO_GRUPOS
.Where(f => f.ID_PESSOA_PROFISSAO_GRUPO == PessoaProfissaoGrupo.ID_PESSOA_PROFISSAO_GRUPO)
.Include(f => PESSOA_PROFISSAO)
.ExecuteAsync(op =>

{

//Rest of the code here

});
