MVC 6, SignalR on .Net461

I am trying to find a way to starts the signalR and Map the Hubs, in a MVC6 application that depends on .Net461 because of NHibernate.

I tried to use "Microsoft.AspNet.SignalR.Server":"3.0.0-beta5" but I keeping get a erro on package restore:

"The dependency Microsoft.AspNet.SignalR.Server 3.0.0-beta5 does not support framework .NetFramework, Version=v4.6.1."

{
  "dependencies": {
    "Domain": "1.0.0-*",

            "frameworkAssemblies": {
                "System.Runtime": {}
            }
        }
    },

    "buildOptions": {
        "emitEntryPoint": true,
        "preserveCompilationContext": true
    },

    "publishOptions": {
        "include": [
            "wwwroot",
            "Views",
            "Areas/**/Views",
            "appsettings.json",
            "web.config"
        ]
    },

    "scripts": {
        "prepublish": [ "bower install", "dotnet bundle" ],
        "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
    }
}

I tried the owin server too, but it don't starts too.

using Owin;
using Microsoft.Owin;
using Microsoft.AspNet.SignalR;

[assembly: OwinStartup(typeof(RLG.SignalR.OwinStart))]

namespace RLG.SignalR
{
    public class OwinStart
    {
        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR();
        }
    }
}

What is the better way to use SignalR in this scenario ?

In order to use SignalR with ASP.Net Core running on net461 framework you have to do a little setup.

1) You need to import the "dnxcore50" framework inside your "net461" configuration.

"frameworks": {
    "net461": {
      "imports": "dnxcore50"
    }
  },

2) You need to create a new file NuGet.config in the root directory of the Web Application project. Once replace the content with the following:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="AspNetCore" value="https://dotnet.myget.org/F/aspnetcore-ci-dev/api/v3/index.json" />
    <add key="NuGet" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>

3) Add the appropriate dependencies to your project.json file.

"Microsoft.AspNetCore.SignalR.Server": "0.2.0-*"
"Microsoft.AspNetCore.WebSockets": "0.2.0-*"

4) Add the appropriate dependencies to your bowser.json file.

"signalr": "^2.2.1"

5) Add the Hubs folder to the root of your Web Application project.

6) In your Startup.cs file add the following line in the Configure(app, env, loggerFactory) method.

app.UseSignalR();

7) In your Startup.cs file add the following line in the ConfigureServices(services) method.

services.AddSignalR(options => options.Hubs.EnableDetailedErrors = true);

At this point setting up your hubs in both C# and JavaScript is identical to older versions or SignalR. I have this successfully working running on the .Net Frameworks targeting 4.6.1.

Use the latest stable (read: non-beta) version, it should work just fine

EDIT: It seems to be version 2.2.1
