使用
在本地开发一堆 Azure 函数
- Windows 10 个 64 位
- Visual Studio代码
- C#/.NET 核心
一切都很好。我能够在本地开发和调试我的 Azure 函数，然后将它们部署到 Azure。然而一天前，我从 netcoreapp2.2 升级到 netcorepp3.1。这是我目前的 settings.json
{
"azureFunctions.deploySubpath": "bin/Release/netcoreapp3.1/publish",
"azureFunctions.projectLanguage": "C#",
"azureFunctions.projectRuntime": "~3",
"debug.internalConsoleOptions": "neverOpen",
"azureFunctions.preDeployTask": "publish",
"azureFunctions.templateFilter": "Verified"
}
现在我仍然可以通过按 F5 启动本地调试会话。但是当我尝试对 localhost:7071 API 地址发出 http 请求时，调试器会话终止并显示以下消息：
...

关于升级过程中发生什么问题的任何想法（我假设升级是导致它的原因）？
编辑：
我注释掉了我正在处理的新功能（编排）。相反，我尝试在调试器中 运行 升级之前使用的旧编排之一，我没有改变。这个旧函数与新函数在同一个本地函数项目中。

如下所示，我更改了我从 [DurableClient] IDurableOrchestrationClient starter [DurableClient] IDurableClient starter 调用的编排的 Http 触发器。这个项目还有五个编排我没改。
在 Stack Overflow 消息之后，调试会话终止后我还收到以下消息：

编辑#5
我确实将我的函数项目中的所有六个编排从 IDurableOrchestrationClient 更改为 IDurableClient。仍然得到同样的错误。
能否将 [DurableClient] IDurableOrchestrationClient starter 更改为 [DurableClient] IDurableClient starter 并试一试？
原来问题出在编排的HttpStart函数中的这段代码：
DurableOrchestrationStatus status;
while (true)
{
status = await starter.GetStatusAsync(instanceId);
if (status.RuntimeStatus == OrchestrationRuntimeStatus.Completed ||
status.RuntimeStatus == OrchestrationRuntimeStatus.Failed ||
status.RuntimeStatus == OrchestrationRuntimeStatus.Terminated)

break;
}

return req.CreateResponse(System.Net.HttpStatusCode.OK, status.Output);

替换上面的代码后，Stack Overflow 异常消失了
