Service Fabric Explorer 运行状况未知答案

【问题标题】：Service Fabric Explorer Health State UnknownService Fabric Explorer 运行状况未知
【发布时间】：2019-09-23 19:13:04
【问题描述】：

我分区中的节点不断在 Health State = OK 和 Health State = unknown 之间切换。有时节点会消失。

我尝试删除服务、应用程序并取消配置类型，然后重新部署，但我遇到了同样的问题。

这是一个 Service Fabric 有状态服务，它在本地运行良好，我遇到的问题只是在我的开发环境中。

我正在使用 5 个节点。

【问题讨论】：

我希望该端口不会被任何其他进程使用。请确保。
可以分享一下应用于测试环境的参数吗？测试环境的一般描述（即多少个节点）？来自ServiceManifest.xml的服务配置？
@OlegKarasik 我已经更新了我的问题。
嗯。您可以检查节点和服务上的 Event 选项卡吗？问题可能是由于以下原因无法启动您的服务可执行文件：缺少程序集/依赖项或框架版本错误。

【解决方案1】：

不确定这部分修复了它。但这就是我所做的，现在它正在工作：

在 ServiceManifest.xml 我添加了HasPersistedState = true:

<StatefulServiceType ServiceTypeName="Integration.Optical.ServiceType" HasPersistedState="true" />

我移动了应用配置代码

ServiceRuntime.RegisterServiceAsync...

从Service.RunAsync() 到Program.Main()
