I've been developing a Web Service (C# WebAPI2) so can simply send messages using SignalR and then store the message transcript within a TSQL database. However, after moving the SignalR hubs within a class library I can't seem to access them now. I have developed a very simply console application to communicate with the Web Service but I am getting a strange exception being thrown.
Here is the exception which is being thrown:
"StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1,

An unhandled exception of type 'System.AggregateException' occurred

The Owin Startup file is placed within the Web Service App_Start folder, here is what it looks like:
using System;
using System.Threading.Tasks;
using Microsoft.Owin;
using Owin;
using Microsoft.AspNet.SignalR;
[assembly: OwinStartup(typeof(Service.App_Start.Startup))]
namespace Service.App_Start
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.Map("/signalr", map =>
{
var hubConfiguration = new HubConfiguration
{
EnableDetailedErrors = true,
EnableJSONP = true
};
map.RunSignalR(hubConfiguration);
});
}
}
}
Many thanks.
I am not sure the details in your case, but for me I found that I was receiving the System.AggregationException:
System.AggregateException was unhandled

I am using a TcpClient with an SslStream. In general everything works fine but we are getting occasional logs of crashes. It seems to be coming from unstable network connections, and I'm unfortunately not able to reproduce it locally despite trying to create "unexpected circumstances":
using Fiddler to replicate a very slow network connection
killing the server application while its sending data
disconnecting network cables
The situation is this:
I call BeginRead like this:
_tcpClientStream.BeginRead(receiveBuffer, 0, receiveBuffer.Length, pfnCallBack, null);
And then EndRead is being called like this:
iRx = _tcpClientStream.EndRead(asyn);
The only place that the iRx is used is to copy the received data to a new array:
var bytes = new byte[iRx];
Array.Copy(receiveBuffer, bytes, iRx);
In the OnDataReceived callback function, I call EndRead on the SslStream, which throws an exception that is handled:
Error in OnDataReceived System.IO.IOException: The read operation failed, see inner exception. ---> System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: size

at System.Net.Security._SslStream.EndRead(IAsyncResult asyncResult)
at System.Net.Security.SslStream.EndRead(IAsyncResult asyncResult)
at XXXXXXX.OnDataRecevied(IAsyncResult asyn)
Normally this is not a problem - this exception is caught and the TcpClient is closed and re-initiated to attempt to reconnect.
However, in this case there is a second Exception that is thrown and comes from one of the UnhandledException error handlers:
AppDomain.CurrentDomain.UnhandledException
Current.DispatcherUnhandledException
Current.Dispatcher.UnhandledException
TaskScheduler.UnobservedTaskException
This stack trace is like this:
System.ObjectDisposedException: Cannot access a disposed object.

Our handling for this type of unhandled error is to display a message to the user that there is a fatal error and the software has to close.
My questions are:
Has anyone ever seen this error before and been able to reproduce the exact out of range exception I'm getting? Despite my attempts to recreate the issue (using the methods described above), I'm not able to ever recreate the exception, it is always the more standard Socket IO exception:
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

at System.Net.Security._SslStream.EndRead(IAsyncResult asyncResult)
at System.Net.Security.SslStream.EndRead(IAsyncResult asyncResult)
at XXXXXXXXX.OnDataRecevied(IAsyncResult asyn)
Is there any way I can handle this exception in my Socket code or is it always going to appear in one of these UnhandledException events? If so, what is the best practice way of handling this? Basically I need some logic in the event handler to identify that the software should not shut down if this specific error is received?
I have a solution that utilises Grapevine to start a server within the Program class.
For some reason though, as soon as I start the program, it crashes when server.Start() is called.
No other parts of the solution are running at this point, so I don't know how that could be happening?
Running in Visual Studio 15, as Administrator, on Windows 10.
Program.cs
using System;
using System.Threading;
using Grapevine.Server;
using QuantConnect.Logging;
namespace QuantConnect.Services
{
class Program
{
/// <summary>
/// QuantConnect C# Services Server:
/// </summary>
static void Main(string[] args)
{
var server = new RESTServer
{
//Host = Configuration.Config.Get("grapevine-host"),
//Port = Configuration.Config.Get("grapevine-port")
Host = Configuration.Config.Get("grapevine-host", "localhost"),
Port = Configuration.Config.Get("grapevine-port", "80")
};
Log.Trace(string.Format("Starting Server On {0}:{1}", server.Host, server.Port));
server.Start(); // Exception occurs here
while (server.IsListening)
{
Thread.Sleep(300);
}
Log.Trace("Server stopped. Press key to continue...");
Console.ReadLine();
}
}
}

So I figured out what the issue was.
I set Grapevine to use port 80.
Port = Configuration.Config.Get("grapevine-port", "80")
Issue was that there was another service on my machine using this port, I changed it to use 8080 and it works fine now.
Port = Configuration.Config.Get("grapevine-port", "8080")
I have followed the tutorial in ( http://www.c-sharpcorner.com/UploadFile/a6fd36/understand-self-host-of-a-web-apiC-Sharp/ ) and ( http://www.c-sharpcorner.com/uploadfile/a6fd36/understanding-how-to-call-the-web-api-from-a-client-applica/ ) but seem to still be getting System.AggregateException on

and
var resp = client.GetAsync(string.Format("api/books/{0}", id)).Result;

I have two console applications:
First one is self hosted ASP.NET WebApi application containing SignalR v2
Second application acts as SignalR client
Following code demonstrates how I initialize SignalR server:
public void Configuration(IAppBuilder app)
{
HttpConfiguration webApiConfiguration = ConfigureWebApi();
app.UseWebApi(webApiConfiguration);
app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
app.MapSignalR(new HubConfiguration() { EnableDetailedErrors = true });
}
And this is how I am trying to establish connection with the server from the client application:
public void Run()
{
HubConnection hubConnection = new HubConnection(this.hubConnectionURL);
hubConnection.TraceLevel = TraceLevels.All;
hubConnection.TraceWriter = Console.Out;
remoteServerHubProxy = hubConnection.CreateHubProxy("SignalRHub");
remoteServerHubProxy.On<Int32, MyModel>("MethodName", new Action<Int32, MyModel>((lid, model) => this.MethodName(lid, model)));
hubConnection.Start().Wait();
}
Whenever Start().Wait() executes, following exception happens clientside:

InnerException:
The interesting part is, that this exception happens only during first ever connection attemp from the client (first connection attempt after server app restart, thats it). If I restart the client or launch another client instance, then it connects fine and SignalR communication works smoothly.
Anyone knows what I am doing wrong here?
I am also attaching SignalR logs both from server and client.

The problem was with the library System.Web.Helpers which is part of ASP.NET MVC installation. As soon as I set the CopyLocal=true for this specific assembly in the References, my problem went away.
I have downloaded DotNetOpenAuth-3.4.6.10357 built it (had to exclude OpenIdOfflineProvider because of build errors) and run OAuthConsumerWpf. After clicking Authorize I got the exception below. Please bear in mind I modified app.config as instructed. This is from the Google tab. I also tried Generic tab with the same results.
What could be wrong here? Shouldn't things as simple as this work out of the box?
