                    client.SendCompleted += (s, e) => {
                        client.Dispose();
                        emailMessage.Dispose();
                    };
                    await client.SendMailAsync(emailMessage);
                }
            }
            await Task.CompletedTask;
        }
        catch (Exception ex)
        {
            _appLogger.CreateLog("SendEmail - " + ex.Message);
        }
    }

Any idea why this behaviour???
