Realtime notification not sent

Question

I am trying to display realtime notification in ASP.NET Boilerplate, but it is not sent.

public override async Task<MessagesDto> Create(MessagesCreateDto input)
{
    var MessagesCore = ObjectMapper.Map<MessagesCore>(input);            
    MessagesCore.UserId = Convert.ToInt32(AbpSession.UserId);
    MessagesCore.CreationId = Convert.ToInt32(AbpSession.UserId);
    MessagesCore.FromUserId = Convert.ToInt32(AbpSession.UserId);
    MessagesCore.CreationTime = DateTime.Now;
    MessagesCore.LastModificationId = Convert.ToInt32(AbpSession.UserId);
    MessagesCore.LastModificationTime = DateTime.Now;

    _stateRepository.Insert(MessagesCore);
    CurrentUnitOfWork.SaveChanges();

    UserIdentifier identifier = new UserIdentifier(1,input.ToUserId);
    await _notificationSubscriptionManager.SubscribeAsync(new UserIdentifier(1, input.ToUserId), "NewMessage");
    await _notificationPublisher.PublishAsync("NewMessage", new SentMessageNotificationData("Test", "New Message"), userIds: new[] { identifier });

    return MapToEntityDto(MessagesCore);
}

SentMessage notification data class:

[Serializable]
public class SentMessageNotificationData : NotificationData
{
    public string SenderUserName { get; set; }

    public string FriendshipMessage { get; set; }

    public SentMessageNotificationData(string senderUserName, string friendshipMessage)
    {
        SenderUserName = senderUserName;
        FriendshipMessage = friendshipMessage;
    }
}

Data is stored in notification table, but no notification message is displaying in client side.

SignalR code in app.component.ts:

ngOnInit(): void {
  if (this.appSession.application.features['SignalR']) {
    SignalRHelper.initSignalR();
  }

  abp.event.on('abp.notifications.received', userNotification => {
    abp.notifications.showUiNotifyForUserNotification(userNotification);
    if (userNotification.notification.data.type === 'Abp.Notifications.LocalizableMessageNotificationData') {
        var localizedText = abp.localization.localize(
            userNotification.notification.data.message.name,
            userNotification.notification.data.message.sourceName
        );

        $.each(userNotification.notification.data.properties, function (key, value) {
            localizedText = localizedText.replace('{' + key + '}', value);
        });

        alert('New localized notification: ' + localizedText);
    } else if (userNotification.notification.data.type === 'Abp.Notifications.MessageNotificationData') {
        alert('New simple notification: ' + userNotification.notification.data.message);
    }
    //Desktop notification
    Push.create("AbpZeroTemplate", {
      body: userNotification.notification.data.message,
      icon: abp.appPath + 'assets/app-logo-small.png',
      timeout: 6000,
      onClick: function () {
        window.focus();
        this.close();
      }
    });
  });
}

Answer 1

i am on netcoreapp2.0

• SignalR is still on 1.0.0-alpha2-final for .NET Core.
• 2.x will only be stable in Q1/Q2 2018.

Update 1

Abp.AspNetCore.SignalR NuGet package has been published.

Read the documentation for SignalR AspNetCore Integration.

You can try it and make the necessary changes to your files. Or just wait for it to be released.

Update 2

You can now download v3.4.1 of the template with the AspNetCore.SignalR preview.
