WebHostBuilder and Autofac support

[shessane]

Hi,

The startup template comes with the new HostBuilder integration, but we still rely on the WebHostBuilder

internal static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
    .ConfigureWebHostDefaults(webBuilder =>
    {
        webBuilder.UseStartup<Startup>();
    })
    .UseAutofac()
    .UseSerilog();

I wonder if anyone managed to get autofac integration with the old WebhostBuilder ?
I tried several ways to do that (register with UseAutofac inside the AddApplication, ConfigureServices with AddAutofac, use BuildServiceProviderFromFactory, tried with netcore3.1 templates...). I get the following exception :

System.InvalidOperationException
HResult=0x80131509

hi

Why can't you use Generic Host?

Hi,

Some of our Apis are hosted on an Azure Service Fabric cluster. The ServiceFabric SDK still needs an IWebHost to declare a listener : https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-reliable-services-communication-aspnetcore#kestrel-in-a-stateless-service

return new KestrelCommunicationListener(serviceContext,
	endpointName, (url, listener) =>
	{
		return new WebHostBuilder()
			.UseKestrel()
			.Configure(....)
			.Build();
	});

Request to add the generic host is tracked here : microsoft/service-fabric-aspnetcore#48

hi

Autofac does not support this.
