I upgraded to .NET 4.5, now SignalR seems insistent on using WebSockets in Firefox/Chrome - even though I'm only on Windows 7 which doesn't have a WebSocket Server.

The request obviously fails:

Firefox can't establish a connection to the server at ws://www.site.local/signalr?connectionData=

How do I force SignalR to forget about Websockets and use Long Polling, or is there a way of setting up Websockets for Windows 7 that I'm missing?

Update.... I'm using SignalR 0.4:

  <package id="SignalR" version="0.4.0" />
  <package id="SignalR.Hosting.AspNet" version="0.4.0.0" />
  <package id="SignalR.Js" version="0.4.0.1" />
  <package id="SignalR.Server" version="0.4.0.0" />
  <package id="SignalR.StructureMap" version="0.4.1" />
