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

another fix for this, from this blog post: http://www.zpqrtbnk.net/posts/appdomains-threads-cultureinfos-and-paracetamol

app.SanitizeThreadCulture();

public static void SanitizeThreadCulture(this IAppBuilder app)
{
        var currentCulture = CultureInfo.CurrentCulture;

        // at the top of any culture should be the invariant culture,
        // find it doing an .Equals comparison ensure that we will
        // find it and not loop endlessly
        var invariantCulture = currentCulture;
        while (invariantCulture.Equals(CultureInfo.InvariantCulture) == false)
            invariantCulture = invariantCulture.Parent;

        if (ReferenceEquals(invariantCulture, CultureInfo.InvariantCulture))
            return;

        var thread = Thread.CurrentThread;
        thread.CurrentCulture = CultureInfo.GetCultureInfo(thread.CurrentCulture.Name);
        thread.CurrentUICulture = CultureInfo.GetCultureInfo(thread.CurrentUICulture.Name);
}
