Transactionscope不用firebird回滚

Question

我在使用事务范围时遇到问题，它没有回滚。这是我的代码，我正在使用

实体版本6.1.3和 Firebird ADO.NET Provider版本5.8.0

我使用了2个数据库，一个用于数据，另一个用于文件。我需要同时提交或不提交

[TestMethod]
public void TestMultiRepositorio()
{

    //UOW uow = new UOW();
    //var repoCliente = uow.IncluiOuObtemRepositorioTipado<ClientesRepositorio>();
    //var repoDocumento = uow.IncluiOuObtemRepositorioTipadoGED<DocumentosRepositorio>();

    //new TransactionScope(TransactionScopeOption.Required, new TransactionOptions() { IsolationLevel = IsolationLevel.ReadCommitted })

    using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Suppress))
    using (IContexto ctx = new ContextoInterlitis())
    using (IContexto ctxGED = new ContextoGED())
    {

        IRepository<Cliente> repoCliente = new ClientesRepositorio(ctx);
        IRepository<Documento> repoDocumento = new DocumentosRepositorio(ctxGED);

        var listaClientes = repoCliente.Buscar(c => c.Nome.Contains("Prefeitura"));
        var cliente = listaClientes.FirstOrDefault();

        cliente.Nome = "Teste";

        ctx.SaveChanges();

        var documento = new Documento() { CaminhoDocumento = @"D:\Formatador.txt" };

        //Add
        repoDocumento.Incluir(documento);

        //Rollback?
        throw new Exception("Teste!");

        ctxGED.SaveChanges();

        cliente.Nome = "Prefeitura de Teste Alterada";

        ctx.SaveChanges();

        scope.Complete();
    }
}
