收到以下错误
Error event: SourceId='System.Hosting',
Property='CodePackageActivation:Code:EntryPoint'.
There was an error during CodePackage activation.Service host failed to activate. Error:0x800700c1`
如果我在 linux 服务结构集群上尝试它，错误会改变一些。因此，由于 windows 没有 bash，因此认为 windows 集群在 entyPoint.sh 脚本上失败了。Linux 集群显然越过了这一点，并且在初始化代码中的某个地方失败了，但仍然找不到在哪里。我添加了
<ConsoleRedirection FileRetentionCount="5" FileMaxSizeInKb="2048"/>
并从 linux 框中下载了所有日志，但没有从控制台中看到任何内容。
Error event: SourceId='System.Hosting',
Property='CodePackageActivation:Code:EntryPoint'.
There was an error during CodePackage activation.The service host terminated with exit code:134

我无法找到有关错误的详细信息，也无法在服务结构环境中调试任何东西，因为它们不会运行。任何帮助表示赞赏！
我已经运行 PerfView 并找到了与包激活相关的事件，但没有提示实际问题是什么。即使没有人知道问题出在哪里，只要获得更多信息的技术帮助就会很棒！
另一件看起来很奇怪的事情是，即使我注释掉 Main() 方法中的所有代码，我仍然会得到完全相同的错误。几乎就像它甚至在框架 dll 或类似的东西上出现之前就失败了，但一切都是 .netcore2 并且我在带有服务结构的机器上安装了运行时
