Autofac integration issue - Ambiguous invocation

[linch90]

• ABP version: 4.2.0.

When I upgrade Abp version to 4.2.0, the AddAutofac extension method display CS0121 error: ambiguous between the "AddAutofac" in the Volo.Abp.Autofac and Autofac.Extensions.DependencyInjection 6.0.0.0

And I also create a brand new project in Abp version 4.2.0, and this problem is still exists.

This issue seems cause by PR #6463 which Add Autofac.Extensions.DependencyInjection package to the Volo.Abp.Autofac module

I can't reproduce this problem.

Just add package Volo.Abp.Autofac 4.2.0, in your module, add codes:

public override void ConfigureServices(ServiceConfigurationContext context)
{
    context.Services.AddAutofac(builder =>
    {

    });
}

the AddAutofac will display ambiguous problem.
This problem only show in Volo.Abp.Autofac 4.2.0, It's ok in Volo.Abp.Autofac 4.1.2 or before

I download a new abp project from https://abp.io/get-started.

1. Install Volo.Abp.Autofac 4.2.0 to {projectName}.Domain
2. add below codes to {projectName}DomainModule.cs

public override void ConfigureServices(ServiceConfigurationContext context)
{
    context.Services.AddAutofac(builder =>
    {

    });
}

• The problem is still exists.
  I don't know if this is a computer environmental related issue, I will try it in another computer to see if the problem is still exists.

You can temporarily resolve it via:

services.AddSingleton<IServiceProviderFactory<ContainerBuilder>>(new AutofacServiceProviderFactory(builder =>
{

}));
