[.NET Core] AspNetCore 2 app using .NET framework does not initialize MicrosoftAppCredentials

I implemented a AspNetCore 2 Bot using .Net 462. I get a notauthorized exception when an intent message is processed by LuisDialog because MicrosoftAppCredentials is not initialized with the credentials.

DialogModule.Load registers MicrosoftAppCredentials without specifying parameters.

builder
       .RegisterType<MicrosoftAppCredentials>()
       .AsSelf()
       .SingleInstance();

When MicrosoftAppCredentials is created this constructor is used with both appId, password set to null :

        public MicrosoftAppCredentials(string appId = null, string password = null)
        {
            MicrosoftAppId = appId;
            MicrosoftAppPassword = password;
            TokenCacheKey = $"{MicrosoftAppId}-cache";
        }

I found a workaround, reregistering MicrosoftAppCredentials :

Conversation.UpdateContainer(
      builder =>
      {
             builder.Register(c => new MicrosoftAppCredentials(microsoftAppId, microsoftAppPassword)).SingleInstance();
      }); 

What is the correct solution for my problem ?

With my workaround, reregistering MicrosoftAppCredentials in the AutoFac container, dialogs and forms are working as expected.

Conversation.UpdateContainer(
      builder =>
      {
             builder.Register(c => new MicrosoftAppCredentials(microsoftAppId, microsoftAppPassword)).SingleInstance();
      });

Here my Code in Startup.cs. I did not test it in Azure.

public void ConfigureServices(IServiceCollection services)
        {
            var loggerFactory = services.BuildServiceProvider().GetRequiredService<ILoggerFactory>() as ILoggerFactoryEx;
            loggerFactory.AddProviderLastErrorOfThread(120, LogLevel.Warning);
            ILoggerEx logger = loggerFactory.CreateLogger("HomeBot") as ILoggerEx;
            services.AddSingleton<ILoggerEx>(logger);

            services.AddSingleton<IConfiguration>(Configuration);
            string microsoftAppId = Configuration[MicrosoftAppCredentials.MicrosoftAppIdKey];
            string microsoftAppPassword = Configuration[MicrosoftAppCredentials.MicrosoftAppPasswordKey];

            services.AddAuthentication().AddBotAuthentication(microsoftAppId, microsoftAppPassword);

            Conversation.UpdateContainer(
                builder =>
                {
                    var store = new InMemoryDataStore();
                    builder.Register(c => store)
                                .Keyed<IBotDataStore<BotData>>(new object())
                                .AsSelf()
                                .SingleInstance();
                    builder.Register(c => new MicrosoftAppCredentials(microsoftAppId, microsoftAppPassword)).SingleInstance();
                });


            services.AddMvc(options =>
            {
                options.Filters.Add(typeof(TrustServiceUrlAttribute));
            });

            var oauthConfig = new OAuthConfiguration("smarthome", null, "smarthome_service", "C4EEED8E-3171-4C9B-B632-614B2C09BC7F", "smarthome", null);
            var devicesProxy = new DevicesProxy("http://www.christian-riedl.com/smarthome/apismarthome", false, logger, new OAuthTokenClient(oauthConfig), true);
            services.AddSingleton(devicesProxy);

        }
