NServiceBus.Unicast.Queuing.QueuesCreator.Install未将NServiceBus 5.0对象引用设置为对象实例

Question

这是否与：https://github.com/Particular/NServiceBus/issues/2561有关？

我使用的是nservicebus 5.0.3和azurestorage队列。

我得到了一个：

   Object reference not set to an instance of an object

在代码成功通过endpointconfig之后启动时，这里是堆栈跟踪。

下面是我的端点配置：

    void IConfigureThisEndpoint.Customize(BusConfiguration configuration)
    {
        var container = BuildContainer();
        configuration.EndpointName(ConfigurationManager.AppSettings["BusQueueName"]);
        configuration.UseTransport<AzureStorageQueueTransport>();
        configuration.UseContainer<AutofacBuilder>(c => c.ExistingLifetimeScope(container));
        configuration.UsePersistence<RavenDBPersistence>();
    }

    private IContainer BuildContainer()
    {
        var builder = new ContainerBuilder();
        var domainAssemblies = AppDomain.CurrentDomain.GetAssemblies();
        builder.RegisterAssemblyModules(domainAssemblies);
        return builder.Build();
    }

最后我把评级从5.03降到5.0，这解决了这个问题。
