MVC5 hangs on MapSignalR when reconnecting after AppPool cycles

Question

I have the following code in my Startup.SignalR.cs:

using Microsoft.AspNet.SignalR;
using Owin;
using System;
using System.Collections.Generic;
using System.         


        

Answer 1

I found the solution here: github.com/SignalR/SignalR/issues/3414 Snip sample:

public void Configuration(IAppBuilder app)
{
    var task = Task.Run(() => app.MapSignalR());
    task.Wait(300);
    //try again if it fails just to be sure ;)
    if (task.IsCanceled) Task.Run(() => app.MapSignalR()).Wait(300);
}
