MultipartBodyLengthLimit is not working in ASP.NET Core Version >= 2.0

[TanvirArjel]

I am trying to upload a file with size more than 30 MB and its throwing the following exception:

HTTP Error 404.13 - Not Found The request filtering module is configured to deny a request that exceeds the request content length.

Then I have configured as follows:

    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<FormOptions>(x =>
        {
            x.ValueLengthLimit = int.MaxValue;
            x.MultipartBodyLengthLimit = int.MaxValue;
            x.MultipartHeadersLengthLimit = int.MaxValue;
        });

        services.AddControllersWithViews();
    }

But still not working!

I have also tried as follows:

    [HttpPost]
    [ValidateAntiForgeryToken]
    [RequestFormLimits(ValueLengthLimit = int.MaxValue, MultipartBodyLengthLimit = int.MaxValue)]
    public ActionResult Create(Employee employee)
    {
        if (ModelState.IsValid)
        {
            return View();
        }

        return View(employee);
    }

And

    [HttpPost]
    [ValidateAntiForgeryToken]
    [DisableRequestSizeLimit]
    public ActionResult Create(Employee employee)
    {
        if (ModelState.IsValid)
        {
            return View();
        }

        return View(employee);
    }

But still nothing is working!

Above configurations have been tried in ASP.NET Core 2.1,2.2,3.0 and 3.1 versions but did not work with any of them.

You're probably hitting Kestrel's default 30 MB (~28.6 MiB) max request body size limit introduced in 2.0.0. You can change it in MVC with the RequestSizeLimitAttribute or disable it entirely with the DisableRequestSizeLimitAttribute.
