I have made a console application which works as a host for signal r and listens to port 8089.When I run wpf application and run that host application on localhost,every thing works fine.Now I have deployed that console application on server.Now when I try to connect ,it doesn't connect through wpf. So then I read that it supports only HTTP protocol and after reading that I made an website which connects to the server on remote server and it is connected successfully. My question is that is there any way I can connect to that server using wpf.I want to make a desktop chat application in which all clients will connect to same server so that it can broadcast.Any help will e appreciated
StartUp.CS
public class Startup
{

{
// Branch the pipeline here for requests that start with "/signalr"
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 already runs under the "/signalr"
// path.
hubConfiguration.EnableDetailedErrors = true;
map.RunSignalR(hubConfiguration);
});
}

Hi there are a few answers,
Here is a MS example https://code.msdn.microsoft.com/windowsdesktop/Using-SignalR-in-WinForms-f1ec847b
here is another example more on wpf http://damienbod.wordpress.com/2013/11/20/signalr-a-complete-wpf-client-using-mvvm/
while the first link says winforms, it covers wpf as well.
In case the link goes down, you want to use this nugget package Microsoft.AspNet.SignalR.Client
The above package supports This package supports WinRT, Silverlight, WPF, console application, and Windows Phone clients, for both .NET 4 and .NET 4.5.
You can find more info about that nugget package at this link http://www.asp.net/signalr/overview/guide-to-the-api/hubs-api-guide-net-client
