Difference between creating a scope using Autofac LifeTimeScope and Asp.net Core DI Extension IServiceScopeFactory

I'm developing an application in Asp.net Core using the Autofac as the default DI and in my integration tests I require some services which before installing the Autofac I was injecting by creating a IServiceScopeFactory and then calling the method CreateScope() to be able to get the services needed, just like the code below:

public void ExampleOfAspNetServiceScope(){    
     var scopeFactory = _testServer.Host.Services.GetRequiredService<IServiceScopeFactory>();

     using (var scope = scopeFactory.CreateScope()){
         var service = scope.ServiceProvider.GetService<ISomeService>();
         // Some stuff...
     }
}

After installing the Autofac into my application I've found in the documentation the interface ILifeTimeScope and now my code could be rewriten as follows:

public void ExampleOfAutofacScope(){    
     var lifetimeScope = _testServer.Host.Services.GetRequiredService<ILifetimeScope>();

     using (var scope = lifetimeScope.BeginLifetimeScope()){
         var service = scope.Resolve<ISomeService>();
         // Some stuff...
     }
}

I did integration tests with both and it seems they behave equally. So, I was wondering what are the differences between the two approaches.

Thanks in advance.
