从fsx脚本编译时,F#管理引用

我需要与SharePoint交互(在内部),并决定尝试F#。仅使用CLI工具就可以做到这一点,或者应该足够简单。

我设法与一个网站进行交互并获得了所需的信息。我为所需的DLL苦苦挣扎,但最后

#if INTERACTIVE
#r @"C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.dll"
#r @"C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"

// seems to be required
#r @"[...]\Microsoft.Online.SharePoint.Client.Tenant.dll.15.0.4615.1001\Microsoft.Online.SharePoint.Client.Tenant.dll"

#r @"[...]\SharePointPnPCoreOnline.3.8.1904\lib\net45\OfficeDevPnP.Core.dll"

#endif

使用Fsi REPLFsi script.fsx解决了问题,但无论是fs文件还是fsx脚本,都无法编译。

我的代码是:

open Microsoft.SharePoint.Client;;

let main () = 
    let authnManager = OfficeDevPnP.Core.AuthenticationManager()
    printfn "%A" authnManager
    0

main()

使用fsi运行:

PS> fsi script.fsx
OfficeDevPnP.Core.AuthenticationManager #OK!

尝试编译:

PowerShell>  fsc --warn:5 -r "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.dll" `
>>      -r "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Runtime.dll" `
>>      -r "absolute\path\to\Microsoft.Online.SharePoint.Client.Tenant.dll.15.0.4615.1001\Microsoft.Online.SharePoint.Client.Tenant.dll" `
>>      -r "absolute\path\to\SharePointPnPCoreOnline.3.8.1904\lib\net45\OfficeDevPnP.Core.dll"  .\script.fsx

为什么会有这种区别?我想念什么?如何使用fsc加载引用(因为nuget安装了很多传递依赖项)?当然,必须同时使用fsc和fsi对它们进行管理! (除非OfficeDevPnP.Core.dll有特定问题...)

答案 0 :(得分:1)

我认为F#Interactive中通过#r引用的DLL必须处于依赖顺序。因此,如果SharePoint DLL依赖于OfficeDevPnp DLL,则需要首先引用OfficeDevPnp DLL(#r行必须在SharePoint #r行之前)。加载DLL之后,您将不得不重置交互式会话,以便以正确的顺序重新加载它们。

通常,在F#交互中加载程序包依赖项非常棘手。有一些{#3}之类的F#工具,您可以看一下它们,这可能会使您的生活更轻松一些。如果您已经有了一个带有所需引用的Visual Studio项目,则另一个选择是使用该项目为脚本文件生成程序包引用。您可以阅读.fsproj文件,并从项目使用的引用中生成#r语句。这样的事情可能会起作用:

#r "System.Xml"
#r "System.Xml.Linq"

open System
open System.IO
open System.Linq
open System.Xml.Linq

let inline isNotNull o = o |> isNull |> not

    Directory.EnumerateFiles(path, "*.*proj") |> Seq.head |> XDocument.Load    

let generateDlls path =
    let projectFile = getProject path
    let references =
        projectFile.Descendants <| XName.Get("HintPath", "http://schemas.microsoft.com/developer/msbuild/2003")
        |> Seq.filter (fun reference -> reference.Value.ToLower().EndsWith(".dll"))

    let projects =
        projectFile.Descendants <| XName.Get("ProjectReference", "http://schemas.microsoft.com/developer/msbuild/2003")
        |> Seq.map (fun reference -> reference.Elements(XName.Get("Name", "http://schemas.microsoft.com/developer/msbuild/2003")).SingleOrDefault())

        |> Seq.map (fun nameElement -> nameElement.Value)
        |> Seq.map (fun reference -> sprintf "../%s/bin/debug/%s.dll" reference reference)

    references
