Hi,

I want to send data from server to client(my console application)wich have a connection to my "LocationHub". I tried to do as described in example from a link but got no result.

What I have tried:

Client Side Code is:
-------------------------

public class Provider
{
static void Main(string[] args)
{
var connection = new HubConnection("http://192.168.1.88:8044/");
var myHub = connection.CreateHubProxy("LocationHub");

//This line it displaying Exception thrown: 'System.AggregateException' in mscorlib.dll

connection.Start().Wait();
myHub.On("addMessage", myString =>
{
Console.WriteLine("This is client getting messages from server :{0}", myString);
});
myHub.Invoke("Chatter", System.DateTime.Now.ToString()).Wait();
Console.Read();
}
}

Server side code is:
-----------------------

class Program
{
static void Main(string[] args)
{
string url = "http://192.168.1.88:8044/";
using (WebApp.Start(url))
{
Console.WriteLine("Server running on {0}", url);
Console.ReadLine();
IHubContext context = GlobalHost.ConnectionManager.GetHubContext();
for (int i = 0; i < 100; i++)
{
System.Threading.Thread.Sleep(3000);
context.Clients.All.addMessage("Current integer value : " + i.ToString());
}
Console.ReadLine();
}
}
}
[HubName("LocationHub")]
public class LocationHub : Hub
{
public void Send(string platform, string message)
{
Clients.All.messageReceived(platform, message);
}
}
}
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.MapSignalR();
}
}

Error:
Exception thrown: 'System.AggregateException' in mscorlib.dll
Additional information: One or more errors occurred.

Inner Exception is:

{"StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:\r\n{\r\n Cache-Control: private\r\n Date: Tue, 20 Dec 2016 09:09:06 GMT\r\n Server: Microsoft-IIS/10.0\r\n X-Powered-By: ASP.NET\r\n Content-Length: 4938\r\n Content-Type: text/html; charset=utf-8\r\n}"}

What is the best solution for implementing this...??
