I'm using signalr to do some real-time events in my web application. I'm trying to force signalr to use the new websocket protocol but it won't, even if I specify it.
$.connection.hub.start({ transport: 'webSockets' })
I definitely have the web socket protocol installed and I am running Windows 8 with IIS 8.
What else do I need to do to enable web sockets support in signalr?

- In Control Panel, click Programs and Features, and then click Turn Windows features on or off. Expand Internet Information Services, expand World Wide Web Services, expand Application Development Features, and then select WebSocket Protocol. Click OK. Click Close.
SignalR. ASP.NET Core SignalR is a library that simplifies adding real-time web functionality to apps. It uses WebSockets whenever possible. For most applications, we recommend SignalR over raw WebSockets.
Check that all the Bot Insight services are running. Check that your firewall settings are configured to accept incoming websocket data. Try to use a different web browser. Restart the Bot Insight Visualization and Bot Insight Scheduler services.
In order to communicate using the WebSocket protocol, you need to create a WebSocket object; this will automatically attempt to open the connection to the server. The URL to which to connect; this should be the URL to which the WebSocket server will respond.
Ensure that your app is using the .NET 4.5 assembly from the SignalR package. If the project is targeting 4.0, or it started that way, then nuget would have added a reference to the 4.0 SignalR assembly which doesn't support websockets. If that's the case, then just uninstall and re-install the signalr packages into your project.

Web Sockets requires .NET 4.5.
If you try running it on Windows Server 8 in the future be sure to activate the Web Sockets feature.
