我试图将带有“角色服务”的“服务结构应用程序”的默认模板从C#转换为F#。

这是github repo

我可以编译所有内容,但是当我将其部署到本地群集时,我会得到System.ArgumentNullException。任何人都知道这是怎么回事吗?

这是堆栈跟踪(抱歉,它是德语):

最佳答案

您的问题非常微妙。我自己偶然发现了这个。

actor界面中的每个参数都必须具有显式名称。感谢艾萨克·亚伯拉罕(Isaac Abraham)在他的blog post中提到了这一点(但是这篇帖子非常过时)

从此更改您的actor界面:

type IMyActor =
  inherit IActor
  abstract member GetCountAsync : unit -> Task<int>
  abstract member SetCountAsync : int -> Task

请执行以下操作:(请注意count参数)
type IMyActor =
  inherit IActor
  abstract member GetCountAsync : unit -> Task<int>
  abstract member SetCountAsync : count: int -> Task

更改之后,您的示例对我来说效果很好。
