How to Inject LazyServiceProvider for console?

[jakeuj]

I created a console project and reference my layered application project.
Console => HostedService.cs

public async Task StartAsync(CancellationToken cancellationToken)
{
    _abpApplication =  await AbpApplicationFactory.CreateAsync<ConsoleAppModule>(options =>
    {
        options.Services.ReplaceConfiguration(_configuration);
        options.Services.AddSingleton(_hostEnvironment);

        options.UseAutofac();
        options.Services.AddLogging(loggingBuilder => loggingBuilder.AddSerilog());
        
        options.Services.AddTransient<HelloWorldAppService>();
    });

    await _abpApplication.InitializeAsync();

    var helloWorldService = _abpApplication.ServiceProvider.GetRequiredService<HelloWorldAppService>();
    // helloWorldService.Logger = _abpApplication.ServiceProvider.GetRequiredService<ILogger<HelloWorldAppService>>();
    await helloWorldService.Test();
}

Application Layer => HelloWorldAppService.cs

public class HelloWorldAppService : MyProjectNameAppService
{
    public Task Test()
    {
        Logger.LogInformation("Test");
    }
}

But I got an error.

Host terminated unexpectedly!
System.NullReferenceException: Object reference not set to an instance of an object.
   at Volo.Abp.Application.Services.ApplicationService.get_Logger()

It's seem LazyServiceProvider isn't be injected, how to mke it work?

It's work!

public HelloWorldAppService(IAbpLazyServiceProvider lazyServiceProvider)
{
    LazyServiceProvider = lazyServiceProvider;
}

_abpApplication =  await AbpApplicationFactory.CreateAsync<ConsoleAppModule>(options =>
{
    options.Services.ReplaceConfiguration(_configuration);
    options.Services.AddSingleton(_hostEnvironment);

    options.UseAutofac();
    options.Services.AddLogging(loggingBuilder => loggingBuilder.AddSerilog());
    
    options.Services.AddTransient<IHelloWorldAppService,HelloWorldAppService>();
});

await _abpApplication.InitializeAsync();

var helloWorldService = _abpApplication.ServiceProvider.GetRequiredService<IHelloWorldAppService>();
await helloWorldService.SayHelloAsync();

Thx.

hi

Property Injection only for types in an assembly containing an AbpModule

[jakeuj]

Should I move GetRequiredService<IHelloWorldAppService> to ConsoleAppModule?
