Prevent ASP.NET(MVC) website to shutting down on exceptions

I know that unhandled exceptions on background threads cause website shutting down so prevent website to shut down, I put below code code to Global.asax for prevent it. 

protected void Application_Error(object sender, EventArgs e)
{
    System.Web.HttpContext context = HttpContext.Current;
    System.Exception ex = Context.Server.GetLastError();

    context.Server.ClearError();

    Elmah.ErrorSignal.FromCurrentContext().Raise(ex);
}

But even this code doesn't prevent to website shut down. What I am missing in here ?

If you really need to manually spawn managed threads, I think the AppDomain.UnhandledException event is your only choice for non-fatal exceptions since Application_Error does not get called for exceptions thrown outside the request processing context.

Depending on what you're doing in your background threads, you may want to switch to the async/await model for I/O-bound operations or TPL in general for CPU-bound tasks.
