ASP.NET Core support

[tallesl]

While the library supports .NET Core, it's not already clear what would be needed to support running it with ASP.NET Core.

You can find out when ASP.NET Core is shutting down with the following Startup.cs (adapted Getting Started):

using System;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;

namespace aspnetcoreapp
{
    public class Startup
    {
        public void Configure(IApplicationBuilder app, IApplicationLifetime lifetime) // added the IApplicationLifetime parameter
        {
            app.Run(context =>
            {
                return context.Response.WriteAsync("Hello from ASP.NET Core!");
            });
            lifetime.ApplicationStopping.Register(() => Console.WriteLine("Bye from ASP.NET Core!")); // added this line
        }
    }
}

But then there's two problems one problem:

• Just calling JobManager.Stop wouldn't be enough since the current implementation doesn't block the running tasks (that's a problem not just for ASP.NET Core by the way);
• It's unclear if shutting down due to idleness plays a role on ASP.NET Core (looks like that's not a problem).

I'm not sure if this is exactly what you're having problems with but as I wrote about this as part of my recent book I thought I'd chip in.

You can do a blocking shutdown to approximate what HostingEnvironment.QueueBackgroundWorkItem (QBWI) does in the full .NET Framework (>= 4.5.2). You can get the ApplicationStopping cancellation token from lifetime (as in your example above) and wait on that. There is also an ApplicationStopped token than hooks in slightly later in the life-cycle.

The docs say that for both; "Shutdown will block until this event completes."

Thank you very much for your input.

There's still a blocking problem on our part (#93) but as soon I got it fixed I'll add an example on how to use the library with ASP.NET Core on our README.

Hi, any improvements for hosting in asp.net core so far?

[tallesl]

Published a JobManager.StopAndBlock method on version 5.1.0.

Add please documentation for use in README.md

[jpsingleton]

Thanks! I've updated ANCLAFS.com (jpsingleton/ANCLAFS@f54b6a7).

@tallesl When will the README be updated?
