QuestionSignalR Connection Problem - Version Mismatch Pin
Kevin Marois8-Aug-19 7:58

I following this article. Everything works great - from a browser.

What we're really after is to use SignalR in a WPF app, so during development I had been hosting in a Console app. Now, I want to host it in IIS.

For testing, I took this sample app and hosted it in IIS on our server. Like I said already, I can chat using from browser to browser.

Now, I'm trying to create a Console app that calls the Send method on the server from my PC:
class Program
 {
     private const string HUB_NAME = "ChatHub";

     private static IHubProxy HubProxy;

     static void Main(string[] args)
     {
         try
         {
             string url = "<a href="http://192.168.50.83:8062">http://192.168.50.83:8062</a>";

             var connection = new HubConnection(url);

             HubProxy = connection.CreateHubProxy(HUB_NAME);
             HubProxy.On<string, string>("send", HandleSendResponse);

             connection.StateChanged += Connection_StateChanged;
             connection.Error += Connection_Error;

             Console.WriteLine($"Connecting to hub named '{HUB_NAME}' at {url}");
             connection.Start().ContinueWith(task =>
             {
                 if (task.IsFaulted)
                 {
                     Console.WriteLine("Connection failed");
                     foreach (var ex in task.Exception.InnerExceptions)
                     {
                         Console.WriteLine(ex.Message);  // <================== EXCEPTION HERE
                     }
                 }
                 else
                 {
                     Console.WriteLine("Connection succeeded");
                 }
             });

         }
         catch (Exception e)
         {
             Console.WriteLine("EXCEPTION OCCURED" + Environment.NewLine + e.ToString());
         }

         Console.WriteLine("Press any key to quit");
         Console.ReadLine();
     }

     private static void Connection_Error(Exception obj)
     {
         Console.WriteLine($"Connection attempt threw '{obj.ToString()}'");
     }

     private static void Connection_StateChanged(StateChange obj)
     {
         Console.WriteLine($"Connection state is '{obj.NewState}'");

         if (obj.NewState == ConnectionState.Connected)
         {
             string[] args = new string[2];
             args[0] = "John Doe";
             args[1] = "Hello there!";

             HubProxy.Invoke("Send", args).ContinueWith(task =>
             {
                 if (task.IsFaulted)
                 {
                     Console.WriteLine("There was an error calling Send: {0}", task.Exception.GetBaseException());
                     Console.WriteLine(task.Status.ToString());
                 }
                 else
                 {
                     Console.WriteLine("Send Complete.");
                 }
             }).Wait();
         }
     }

     private static void HandleSendResponse(string name, string message)
     {
         Console.WriteLine($"Server returned: '{message}' from '{name}'");
     }
 }
I'm getting the exception "You are using a version of the client that isn't compatible with the server. Client version 2.0, server version 1.3."

This looks pretty straightforward, but I've checked twice - both the server and client console app are using SignalR 2.0.0.

In the case of the browser, the jquery versions also look up to date, but my console app should care about that.

I've Googled this and everyone seems ot say the same thing as the message. But from what I can see the versions are correct.

Anyone have any ideas?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
