Question

Now I am developing server desktop application in c#(visual Studio 2012) using SignalR .

Client Application using Mosync Mobile application(Mobile Platform Independent)

When server application and client application is on same machine(localhost), communication is successfully created and data feed from server to client is working fine. But When i put server application in remote server, Mosync client application is not communicate with server. Could any one help me?

Server side code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

using System.Reflection;

using Microsoft.AspNet.SignalR;
using Microsoft.Owin.Hosting;
using Microsoft.Owin.Cors;
using Microsoft.Owin;
using Owin;

namespace SampleSignalRServer
{
    public partial class Form1 : Form
    {
    private IDisposable signalR { get; set; }
    const string ServerURI = "http://localhost:8080";
    MyHub h = new MyHub();
    public Form1()
    {
        InitializeComponent();
    }

    private void btnServerStart_Click(object sender, EventArgs e)
    {
        writeToConsole("Starting server...");
        btnServerStart.Enabled = false;
        Task.Run(() => StartServer());
    }
    private void StartServer()
    {
        try
        {
            signalR = WebApp.Start(ServerURI);

        }
        catch (TargetInvocationException)
        {
            writeToConsole("Server failed to start. A server is already running on" + ServerURI);
            this.Invoke((Action)(() => btnServerStart.Enabled = true));
            return;
        }
        this.Invoke((Action)(() => btnServerStart.Enabled = true));
        writeToConsole("Server started at" + ServerURI);
    }
    public void writeToConsole(string message)
    {
        if (RichTextBoxConsole.InvokeRequired)
        {
            this.Invoke((Action)(() => writeToConsole(message)));
            return;
        }
        RichTextBoxConsole.AppendText(message + Environment.NewLine);
    }

    private void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {

        }
    }
    private void btnSend_Click(object sender, EventArgs e)
    {
        string msg = txtMessage.Text;
        h.Receive(msg);
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        string message = "hi";
       // h.Receive(message);
    }


}
class Startup
{
    public void Configuration(IAppBuilder app)
    {
        app.UseCors(CorsOptions.AllowAll);
        app.MapSignalR();
    }
}
public class MyHub : Hub
{
    public void Send(string name, string message)
    {
        Clients.All.addMessage(name, message);
        Program.mainform.writeToConsole(name + " : " + message);
    }
    public void Receive(string msg)
    {
        var context = GlobalHost.ConnectionManager.GetHubContext<MyHub>();
        context.Clients.All.addMessage("Admin", msg);
    }
    public override Task OnConnected()
    {
        Program.mainform.writeToConsole("Client Connected:" + Context.ConnectionId);

        return base.OnConnected();
    }
    public override Task OnDisconnected(bool stopCalled)
    {
        Program.mainform.writeToConsole("Client DisConnected: " + Context.ConnectionId);
        return base.OnDisconnected(stopCalled);
    }

}

Assuming your code is ok, which it does at first glance, then it is probably either an IIS or network/infrastructure issue. Have you investigated this possibility ?

SignalR is supported on IIS 7.0 and 7.5, but support for extensionless URLs must be added. To add support for extensionless URLs, see http://support.microsoft.com/kb/980368
