So, I have a SignalR self hosted console application and a website running on WAMP. Everything works just fine when I'm using localhost as domain-name. Obviously this only works locally.
I want it to work on other puter too. So I have tried to change localhost to my local ip, both in the c# console application, and also on the website. The console application crashes when I have my local ip, with the error :
An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll
I have also tried to use * instead of localhost in the console application. Like this:
string url = "http://*:8080/servers/2/";
Same goes there, it crashes. What am I doing wrong?
Console application code:
namespace SignalRSelfHost
{
class Program
{
public static IPAddress ipAd { get; set; }
public static TcpListener myList { get; set; }
static void Main(string[] args)
{
// This will *ONLY* bind to localhost, if you want to bind to all addresses
// use http://*:8080 to bind to all addresses.
// See .httplistener.aspx
// for more information.
string url = "http://localhost:8080/servers/2/";
using (WebApp.Start(url))
{
Console.WriteLine("Server running on {0}", url);
Console.ReadLine();
}
}
}
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 unmenting 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.
map.RunSignalR(hubConfiguration);
});
}
}
public class MyHub : Hub
{
public void Send(string message)
{
Clients.All.addMessage(message);
}
}
}
And my website's code:
<input type="text" id="message" />
<input type="button" id="sendmessage" value="Send" />
<input type="hidden" id="displayname" />
<ul id="discussion"></ul>

<!--Add script to update the page and send messages.-->
<script type="text/javascript">

var url = "http://localhost:8080/servers/<?php echo $server->row()->id; ?>/signalr";
//Set the hubs URL for the connection
$.connection.hub.url = url;
// Declare a proxy to reference the hub.
var chat = $.connection.myHub;
// Create a function that the hub can call to broadcast messages.
chat.client.addMessage = function (message) {
// Html encode display name and message.
var encodedMsg = $('<div />').text(message).html();
// Add the message to the page.
$('#discussion').append('<li>' + encodedMsg + '</li>');
};
// Get the user name and store it to prepend to messages.
//$('#displayname').val(prompt('Enter your name:', ''));
// Set initial focus to message input box.
//$('#message').focus();
// Start the connection.
$.connection.hub.start().done(function () {
$('#sendmessage').click(function () {
// Call the Send method on the hub.
chat.server.send($('#message').val());
// Clear text box and reset focus for next ment.
$('#message').val('').focus();
});
});
});

- Can you able to run from browser debug? I want to know where it is failing, to invoke signalR or something else? As per current error it looks like .NET library invocation error. – Ranajit Chatterjee Commented Sep 4, 2014 at 20:36
-
TargetInvocationExceptionshould have a non-null InnerException which should tell you more details about the error you are seeing. Post the full exception details otherwise it can be just anything. – Pawel Commented Sep 4, 2014 at 21:10 - Like this? pastebin./c9KnKzR7 – Dexception Commented Sep 4, 2014 at 21:27
