Increase upload limit on Azure Web Service / Razor Pages

I have a Razor Pages app with a file upload page. I want to allow up to 60 MB uploads on that page. I can get do this locally by adding a <requestLimits maxAllowedContentLength="62914560" /> tag to my local applicationhost.config file in the .vs directory, but that doesn't help the deploy.

Here's what I've tried

  1. Adding [RequestFormLimits(MultipartBodyLengthLimit = 60 * 1024 * 1024)] and [RequestSizeLimit(60 * 1024 * 1024)] to the PageModel for the page in question
  2. Adding services.Configure<FormOptions>(options => { options.MultipartBodyLengthLimit = 60 * 1024 * 1024; }); to my Startup.cs
  3. Adding a middleware handler with app.UseWhen(context => context.Request.Path.StartsWithSegments("/mypagepath"), appBuilder => { appBuilder.Features.Get<IHttpMaxRequestBodySizeFeature>().MaxRequestBodySize = null; });
  4. Adding a Web.config file to the root of the project with the <requestLimits> tag. If I deploy that file the whole app stops working.

Everything works locally but when I deploy to my Azure App Service, I get this error

The page was not displayed because the request entity is too large.

If you add web.config file, you don't need to add anything in your code.

In .net core project, you also can use web.config file.

  <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="62914560" /> <!--60MB-->
      </requestFiltering>
    </security>
  </system.webServer>
