azure持久函数“未找到”

我正在尝试运行Microsoft持久函数示例。 The article is here . 当我运行functions项目(c,visual studio)时,它似乎启动得很好,cli会启动,我会初始化主机并列出两个启动url。

Http Functions:

        HttpStart: http://localhost:7071/orchestrators/{functionName}

        HttpSyncStart: http://localhost:7071/orchestrators/{functionName}/wait

但是,当我导航到要启动的函数时,它会告诉我“未找到”,例如通过:

http://localhost:7071/orchestrators/E1_HelloSequence

我得到“找不到”:

[30/05/2018 21:17:40] Executed HTTP request: {
[30/05/2018 21:17:40]   "requestId": "9b82e4b2-c0df-4cf4-a191-ce7d7709d30f",
[30/05/2018 21:17:40]   "method": "GET",
[30/05/2018 21:17:40]   "uri": "/orchestrators/E1_HelloSequence",
[30/05/2018 21:17:40]   "authorizationLevel": "Anonymous",
[30/05/2018 21:17:40]   "status": "NotFound"
[30/05/2018 21:17:40] }

你知道为什么这些最基本的样本会让我头痛吗?我试过很多不同的组合,都没有用。
