SignalR hubs cross-domain is broken in Chrome and Firefox, long polling works in IE11 -
i'm using signalr 2.0.3. can't find working, reliable examples version of signalr.
on server, have this:
app.map("/signalr", map => { map.usecors(corsoptions.allowall); var cfg = new hubconfiguration() { enablejsonp = true }; cfg.enabledetailederrors = true; map.runsignalr(cfg); }); on client, have this:
var settings = function() { var connectionurl = window.location.protocol + "//signalr.mydomain.com/signalr"; var querystring = "email=jdentler%40dwhomes.com\u0026windowsaccountname=jdentler"; homecoming { connectionurl: connectionurl, querystring: querystring }; }(); $.connection.hub.url = settings.connectionurl; $.connection.hub.qs = settings.querystring; $.connection.hub.logging = true; $.connection.hub.start(); here's output chrome 35:

it turns out request connect failing. because 1 of hubs replying new connection info blew json serializer. resulting 500 response didn't have cors headers, well-behaving browsers ignored response. fiddler friend. error pipeline signalr docs.
