安装 Windows 服务时出错(在 F# 中)

Error Installing a Windows Service (in F#)

我的问题如下: 当我尝试安装我的 Windows 服务时,出现以下错误:

片段: ... No public installers with the RunInstallerAttribute.Yes attribute could be found in the <path to exe> assembly. ...

我关注这个tutorial

我有一个 Program.fs 文件包含:

[<RunInstaller(true)>]
type public FSharpServiceInstaller() =
    inherit Installer()
    do
        < some logic, doesn't really matter >

这应该足够了,事实上,我什至不认为我需要在类型定义中添加 public 关键字。使用 InstallUtil.exe 安装此可执行文件会出现与使用以下代码安装它相同的错误:

[<EntryPoint>]
let main args =

    if Environment.UserInteractive then
        let parameter = String.Concat(args);
        match parameter with
        | "-i" -> ManagedInstallerClass.InstallHelper [| Assembly.GetExecutingAssembly().Location |]
        | "-u" -> ManagedInstallerClass.InstallHelper [| "/u"; Assembly.GetExecutingAssembly().Location |]
        | _ -> printf "Not allowed!\n" 
    else 
        ServiceBase.Run [| new CreditToolsService() :> ServiceBase |];
    0

我已经在 PowerShell、cmd 和 Visual Studio CLI 中尝试 运行 这个脚本作为管理员和我的普通帐户,但我总是遇到同样的错误。如果有人知道我做错了什么,我将不胜感激。

进行现场制作示例

虽然认为它需要与 InstallUtil.exe 一起安装。

可能不是编码中最好的时刻,但该特定服务代码或多或少来自 Don Syme:http://blogs.msdn.com/b/dsyme/archive/2011/05/31/a-simple-windows-service-template-for-f.aspx,所以可能没问题,但 "surrounding" 代码的其余部分该存储库可能不是惯用的 ;-)

Don Symes 博客也解释了很多,因此应该很容易使它适应您的需要。它还链接到 VS Gallery 上的 Win 服务模板:http://blogs.msdn.com/b/mcsuksoldev/archive/2011/05/31/f-windows-application-template-for-windows-service.aspx

好的,所以开始...

我查看了 user1758475 提供的代码,然后随机开始将解决方案复制粘贴到应用程序中。 Don Symes 的解决方案 "just worked" 我终于明白了原因:在我的源代码中我没有(他也有)命名空间声明。看来这就是罪魁祸首!添加命名空间后,安装程序运行得非常棒。

正如 Curt Nichols 指出的那样,安装程序不应位于模块中,因为模块有效地隐藏了调用代码中的类型。

感谢您帮助解决这个问题。
