Please see http://go.microsoft.com/fwlink/?LinkId=272764 for more information on using SignalR.
Upgrading from 1.x to 2.0
-------------------------
Please see http://go.microsoft.com/fwlink/?LinkId=320578 for more information on how to
upgrade your SignalR 1.x application to 2.0.
Mapping the Hubs connection
----------------------------------------
SignalR Hubs will not work without a Hub route being configured. To register the default Hubs route, create a class called Startup
with the signature below and call app.MapSignalR() in your application's Configuration method. e.g.:
using Microsoft.AspNet.SignalR;
using Owin;
namespace MyWebApplication
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.MapSignalR();
}
}
}
Enabling cross-domain requests
---------------------------------------
To enable CORS requests, Install-Package Microsoft.Owin.Cors and change the startup class to look like the following:
using Microsoft.AspNet.SignalR;
using Microsoft.Owin.Cors;
using Owin;
namespace MyWebApplication
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.Map("/signalr", map =>
{
// Setup the cors middleware to run before SignalR.
// By default this will allow all origins. You can
// configure the set of origins and/or http verbs by
// providing a cors options with a different policy.
map.UseCors(CorsOptions.AllowAll);
var hubConfiguration = new HubConfiguration
{
// You can enable JSONP by uncommenting line below.
// JSONP requests are insecure but some older browsers (and some
// versions of IE) require JSONP to work cross domain
// EnableJSONP = true
};
// Run the SignalR pipeline. We're not using MapSignalR
// since this branch is already runs under the "/signalr"
// path.
map.RunSignalR(hubConfiguration);
});
}
}
}
Starting the Web server
--------------------------------
To start the web server, call WebApp.Start<Startup>(endpoint). You should now be able to navigate to endpoint/signalr/hubs in your browser.
using System;
using Microsoft.Owin.Hosting;
namespace MyWebApplication
{
public class Program
{
static void Main(string[] args)
{
// This will *ONLY* bind to localhost, if you want to bind to all addresses
// use http://*:8080 or http://+:8080 to bind to all addresses.
// See http://msdn.microsoft.com/en-us/library/system.net.httplistener.aspx
// for more information.
using (WebApp.Start<Startup>("http://localhost:8080/"))
{
Console.WriteLine("Server running at http://localhost:8080/");
Console.ReadLine();
}
}
}
}
