autofac - 如何在通用主机中访问 Autofac 构建的容器

Question

我知道在 ASP.NET Core 中你可以使用GetAutofacRoot：

public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
{
    // If, for some reason, you need a reference to the built container, you
    // can use the convenience extension method GetAutofacRoot.
    this.AutofacContainer = app.ApplicationServices.GetAutofacRoot();
}

...但这在使用通用主机时似乎不可行。我正在尝试注册一个 ServiceLocator：

// Perform registrations and build the container.
var container = builder.Build();

// Set the service locator to an AutofacServiceLocator.
var csl = new AutofacServiceLocator(container);
ServiceLocator.SetLocatorProvider(() => csl);
