不能与AutoFac解决Azure的服务织物服务甚至是所有的对象都可以

Question

我试图使用Autofac注入：

Unhealthy event: SourceId='System.RA', Property='ReplicaOpenStatus', HealthState='Warning', ConsiderWarningAsError=false.
Replica had multiple failures during open on _Node_0. API call: IStatelessServiceInstance.Open(); Error = Autofac.Core.DependencyResolutionException (-2146233088)
An error occurred during the activation of a particular registration. See the inner exception for details. Registration: Activator = ServiceFabricProxy (DelegateActivator), Services = [MYSERVICE.ServiceFabric.ServiceFabric], Lifetime = Autofac.Core.Lifetime.CurrentScopeLifetime, Sharing = None, Ownership = ExternallyOwned ---> An error occurred during the activation of a particular registration.

这些错误总是令人沮丧，因为他们不停止的Visual Studio！

public ServiceFabric(StatelessServiceContext context, ServiceLoggerFactory serviceLoggerFactory, ServiceConfiguration configuration)
    : base(context)
{
    Argument.IsNotNull(() => context);
    Argument.IsNotNull(() => serviceLoggerFactory);
    Argument.IsNotNull(() => configuration);

    _log = serviceLoggerFactory.EnrichLoggerForStatelessServiceContext(this);
    _log.Information($"Service constructed {GetType().FullName}");
}

我已经验证了，在我的构造函数的类已注册：

public class NodeAutofacModule : Module
{
    protected override void Load(ContainerBuilder builder)
    {
        var assembly = typeof(GlobalAutofacModule).Assembly;
        var appName = assembly.GetName().Name;
        var appVersion = assembly.InformationalVersion();

        builder.Register<ILogger>(container => LoggingHelper.ConfigureLogging(appName, appVersion))
            .SingleInstance();

        builder.RegisterType<ServiceLoggerFactory>()
            .SingleInstance();

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

        // TODO: Register services here
    }
}

我觉得AutoFac很无奈与当它无法解析的构造函数的工作。

有什么方法来获得更多的信息，当这种情况发生？

当我的服务织物服务启动时，我创造我的容器。

在SF错误切堆栈跟踪实在是烦人。但有一种方式来获得错误的详细信息。试试你的容器的配置后进行如下：

using (var c = builder.Build())
{
    var s = c.Resolve<ServiceFabric>();
}

因此，你会得到访问完整的异常信息，并能指出问题。
