Service Fabric Explorer运行状况未知

Question

我的分区中的节点一直在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，取消提供类型，然后重新部署，但我得到了同样的问题。

​

​

它是一个service Fabric有状态服务，并且在本地运行良好，我遇到的问题只出现在我的开发环境中。

我使用了5个节点。

Answer 1

不确定是哪部分修复了它。但这就是我所做的，现在它起作用了：

在ServiceManifest.xml中，我添加了HasPersistedState = true

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

我移动了应用程序配置代码

ServiceRuntime.RegisterServiceAsync...

从Service.RunAsync()到Program.Main()
