Error Restore package Abp.AspNetCore.SignalR

I created an ASP.NET Core project using the template module zero, but when restoring the package it is displaying the following error:

Unable to find package Microsoft.AspNetCore.SignalR with version (> = 1.0.0-preview1-27891)
  - Found 3 version (s) in nuget.org [Nearest version: 1.0.0-alpha2-final]

I went in the nuget and checked that the Install-Package package Abp.AspNetCore.SignalR references the Microsoft.AspNetCore.SignalR (> = 1.0.0-preview1-27891) version, which does not exist. The latest version available for this SignalR package is version 1.0.0-alpha2-final

Add this file to the same folder as your .sln file: NuGet.Config

I have successfully added SignalR to my asp core solution (ASP Zero). For some reason the notification is not real time and I have to still refresh the page to get the notification bell jingling! All I have is a button on my Angular page which would call a service to publish a notification! in the same page where the button is I have defined a function to register to a notification: registerEvents(): void { abp.event.on('abp.notifications.received', function (userNotification) { alert(userNotification); }); } seems the following trigger within the abp.signalr-client.j is get fired at all: //Register to get notifications connection.on('getNotification', function (notification) { abp.event.trigger('abp.notifications.received', notification); });

thanks
