aspnetcore app.UseWebpackDevMiddleware throws System.OperationCanceledException

[justinushermawan]

I'm using a Webpack Middleware from Microsoft.AspNetCore.SpaServices.Webpack to build an aspnetcore app with VanillaJS for the client app and using Webpack module bundler for it. Here is my Startup's Configure(...):

if (env.IsDevelopment())
{
    app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions
    {
        ProjectPath = Path.Combine(Directory.GetCurrentDirectory(), "ClientApp"),
        HotModuleReplacement = true
    });

    app.UseDeveloperExceptionPage();
}

But every time I cancel the running app with CTRL-C, it throws an exception like this:

Unhandled exception. System.OperationCanceledException: The operation was canceled.
   at System.Threading.CancellationToken.ThrowOperationCanceledException()
   at System.Threading.CancellationToken.ThrowIfCancellationRequested()
   at Microsoft.Extensions.Hosting.Internal.Host.StopAsync(CancellationToken cancellationToken)

   at Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.Run(IHost host)
   at Revolt.Program.Main(String[] args) in C:\Workspace\revolt\Revolt\Program.cs:line 16

What's wrong here?

Thanks for contacting us. We have obsoleted the WebpackDevMiddleware in 3.0. We do not plan to make any changes to it, unless there are any security concerns. This looks like a non-major bug we don't plan to address.
