Question

我们经常遇到断断续续的问题，即持久功能在闲置后无法启动（消耗计划）。

查看日志，我们发现它涉及DI问题和/或无法从以下位置开始：

ScriptStartupTypeLocator.cs

这里的开发人员不太高兴，我们正在努力诊断问题！任何MS文档中都没有细节，也没有关于该问题的许多报告。

任何帮助都会超级有帮助。

//进一步调查

最终通过应用洞察力找到了更多详细信息：

消息：

Method not found: 'Void DurableTask.AzureStorage.AzureStorageOrchestrationServiceSettings.set_FetchLargeMessageDataEnabled(Boolean)'.

失败的方法：

DryIoc.Microsoft.DependencyInjection.DryIocAdapter+<>c__DisplayClass3_0.<RegisterDescriptor>b__0

考虑到上述情况，似乎内置的IoC容器无法注册？

空闲后，Azure持久功能无法启动（间歇性）
