使用F#的Service Fabric无法正常工作

我尝试转换" Service Fabric Applicatoin"的默认模板。与"演员服务"从C#到F#。

这是github repo

我可以编译所有内容,但当我将其部署到本地群集时,我得到System.ArgumentNullException。有没有人知道这里有什么问题?

这是堆栈跟踪(它是德语,对不起):

你的问题非常微妙。我自己偶然发现了这一点。

actor接口中的每个参数都必须具有显式名称。感谢Isaac Abraham在blog post中提到这一点(但这篇文章已经过时了)

更改您的演员界面:

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

以下内容:(注意计数参数)

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

在此更改后,您的示例对我来说很好。
