即使所有对象都可用，也无法使用 AutoFac 解析 Azure Service Fabric 服务

Question

我正在尝试使用 Autofac 进行注入：

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，因为它们不会停止 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}");
}

我已验证构造函数中的类已被注册：

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
    }
}

我发现当 AutoFac 无法解析构造函数时，使用起来真的很令人沮丧。

发生这种情况时，有什么方法可以获得更多信息吗？

我正在 Service Fabric 服务启动时创建我的容器。

Cut stacktrace in SF 错误真的很烦人。但是有一种方法可以获取错误的更多详细信息。配置容器后尝试以下操作：

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

因此您将能够访问完整的异常信息并能够指定问题。
