好的，我收到了一个堆栈错误。它被抓住的文件在这里

我到处寻找，它引用版本3.0.5作为可能的解决方案。任何帮助表示赞赏！

我收到的错误是：

Answer 1

为了避免双向依赖关系异常，您可以实现延迟加载，如下所示。

    private readonly Lazy<IService> _service;

    public MainService(Lazy<IService> service)
   {
     _service=service;
   }

您现在可以将服务中的方法称为

_service.Value.Method()

我认为这应该可以解决你的问题

Answer 2

我们也面临着同样的问题，将StructureMap nuget软件包更新到3.1.5版本已经解决了我们的问题。

Answer 3

在我的情况下，有一种依赖关系是未从API加载实现。

API上安装的Newtownsoft版本低于实现，因此，当尝试加载该版本时，它失败了。错误确实令人误解。我必须在实现上评论字段和构造函数，然后显示真正的错误。然后只需更新Newtosoft即可修复所有问题。

检测到双向依赖关系
