Hi all?

I am using SignalR v0.2.0-alpha1 in ASP.NET Core 2.0, but I'm getting http error 404 when I called http://localhost:51772/signalr/hubs

This is part of my startup

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();
            services.AddSignalR();
        }

and this is my bower.json

{
  "name": "asp.net",
  "private": true,
  "dependencies": {
    "bootstrap": "3.3.7",
    "jquery": "2.2.0",
    "jquery-validation": "1.14.0",
    "jquery-validation-unobtrusive": "3.2.6",
    "signalr": "2.2.2"
  }
}

Last, this is my index.cshtml on Home views

@{ 
    ViewData["Title"] = "Home Page";
}

<span id="MessageDisplay">

</span>
<script src="~/lib/jquery/dist/jquery.min.js"></script>
<script src="~/lib/signalr/jquery.signalR.min.js"></script>
<script src="Signalr/hubs"></script>
<script>
    var hubProxy = $.connection.hub.createHubProxy("myHub");
    $.connection.hub.start().done(function () { 
        alert('HUB Started');
    });
</script>

Need help please..

Hi jsiahaan,

How do you define the Hub on the server side? Could you please share the code of the Hub here?

This is part of my startup

How do you Use the Signalr inside the Startup/Configure method?

Here is an article which shows how to use SignalR with ASP.NET Core 2.0, please take it as reference.
