Timeouts with long running ASP.NET MVC Core Controller HTTPPost Method

Question

I make use of ajax call in my ASP.NET Core MVC view pages

MyView.cshtml

          $.ajax({
                processData: false,
                contentType: false,
                data: new FormData(this),
                type: $(this).attr('method'),
                url: $(this).attr('action'),
                cache: false,
                success: function (data) {
                        $('#mydiv).html(data);
                        $('#bootstrapModal).modal('show');

Controller Post method"

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> MyLongRunningMethod(MyViewModel viewModel)
    {
        await MyProcess.Longprocess1();
        await MyProcess.Longprocess2();
        await MyProcess.Longprocess3();
        await MyProcess.Longprocess4();
        return PartialView("_MyPartialPage");
    }

This works but only has an issue for a long running process. I get the following error during debug mode when the process takes longer than around 2 minutes

I understand this is to do with expiration timeout

in previous versions of ASP.NET MVC you can apparently increase the timeout in your asp.net controller action.

HttpContext.Current.Server.ScriptTimeout = 90000;

However this doesn't exist in ASP.NET Core

I want to increase the timeout for debugging and deployment for a particular asp.net controller.

For production I can set it globally in the web.config by adding requestTimeout to the existing httpPlatform tag. e.g. for 10 minutes

<httpPlatform requestTimeout="00:10:00" ....

A similar question was asked but the answer giving using an CancellationToken but reading it, it doesn't seem it can help me with the timeouts.

1. How do I set the timeouts in Visual Studio 2015 debug mode like I can do when I deploy it?
2. IS there a per controller timeout setting like there was in ASP.NET 4?

Answer 1

But in .Net Core 2.0 there is no web.config file in project. It generate automatically.

I solved the problem by adding .UseKestrel(...) to the BuildWebHost function in Program.cs file as follows:

public static IWebHost BuildWebHost(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>()
        .UseKestrel(o => { o.Limits.KeepAliveTimeout = TimeSpan.FromMinutes(10); })
        .Build();
}
