System.ObjectDisposedException: 'Cannot access a disposed object. Object name: 'The log file has been disposed.'.'

The Serilog maintainers want you to have a great experience using Serilog, and will happily track down and resolve bugs. We all have limited time, though, so please think through all of the factors that might be involved and include as much useful information as possible 😊.

ℹ If the problem is caused by a sink or other extension package, please track down the correct repository for that package and create the report there: this tracker is for the core Serilog package only.

Description
What's going wrong?
I have the following code snippet in Program.cs:

    builder.Host.UseSerilog((ctx, svc, config) =>
    {
        config.ReadFrom.Configuration(ctx.Configuration).ReadFrom.Services(svc).Enrich.FromLogContext();
    }, preserveStaticLogger: true);
    builder.Services.AddLogging(builder => builder.AddSerilog(dispose: true));

Debug session hits the following exception:

Reproduction
Please provide code samples showing how you're configuring and calling Serilog to produce the behavior.

Expected behavior
No exception.

Relevant package, tooling and runtime versions
What Serilog version are you using, on what platform?

Additional context
ASP.Net Core 9, all nuget packages are the latest versions.

The second line, builder.Services.AddLogging(... should not be necessary after calling builder.Host.UseSerilog(. Only one or the other is necessary. HTH!

How can I have both Serilog and Microsoft.Extensions.Logging ILogger and ILggerFactory (To create a Logger)? For example, in integration test with WebApplicationFactory:

public class CustomWebApplicationFactory<TStartup> : WebApplicationFactory<TStartup>, IAsyncLifetime where TStartup : class
{
    protected override void ConfigureWebHost(IWebHostBuilder builder)
    {
        // Route the application's logs to the xunit output
        builder.UseEnvironment("IntegrationTests");
        builder.ConfigureLogging((p) => p.SetMinimumLevel(LogLevel.Debug));
        builder.ConfigureServices((context, services) =>
        {
            // Create a new service provider.
            services.Configure<GrpcConfig>(context.Configuration.GetSection(nameof(GrpcConfig)));
            services.AddScoped<SignInManager<AppUser>>();
        });
    }
    public async ValueTask InitializeAsync()
    {
        using (var scope = Services.CreateScope())
            try
            {
                var scopedServices = scope.ServiceProvider;
                ILoggerFactory loggerFactory = scopedServices.GetRequiredService<ILoggerFactory>(); //
                ILogger logger = loggerFactory.CreateLogger<CustomWebApplicationFactory<TStartup>>();
                // Seed the database with test data.
                logger.LogDebug($"{nameof(InitializeAsync)} populate test data..."); XXX: I don't see output of this line at all
            }
            catch (Exception ex)
            {
                Console.WriteLine($"{nameof(InitializeAsync)} exception! {ex}");
                throw;
            }
    }
}
