在f＃脚本中执行c＃代码有意外的行为

我有一个F＃伪脚本，它与Nuge.Core一起使用来提取包文件。如果我尝试用c＃控制台应用程序来做到这一切，一切正常。但是，如果我在f＃伪脚本中执行完全相同的脚本，则它不起作用。这里有这么多的依赖关系，我不知道到哪里寻找帮助：docker.dotnet，fake，f#，nuget.core在f＃脚本中执行c＃代码有意外的行为

要重现这一点，你需要下载Docker.DotNet.2.124.3.nupkg

您需要的C＃示例控制台应用程序并安装nuget.core nuget软件包。这工作！

class Program 
{ 
    static void Main() 
    { 
     var zip = new NuGet.ZipPackage(@"Docker.DotNet.2.124.3.nupkg"); 
     foreach (var file in zip.GetFiles()) 
     { 
      System.Console.WriteLine(file.Path); 
     } 
    } 
}

为F＃示例你并排需要这两个文件的一面： https://gist.github.com/mynkow/e6f0e550fcacc268dd1e9b743e17d344

我与所有可能的依赖性的5个最新版本的尝试并且结果完全相同=> c＃正在工作，f＃不是。你有任何线索或任何你可以建议我试图解决这个问题吗？

肮脏的解决方案：
这是Docker.DotNet.2.124.3.nupkg怎么看起来像inside
如果我删除例如netstandard1.6一切正常。这意味着问题在nuget.core，对不对？但为什么它在C＃控制台应用程序中工作？不知道！

UPDATE：我能够从F＃控制台应用程序

您确定在两种情况下都引用了相同版本的'NuGet'库吗？ –

是的，在样品提供这不明确，但这是第一件要检查。此外，我已尝试过每个依赖项的多个版本。 – mynkow

您可以尝试用fsi.exe调用脚本吗？如果它适用于fsi而不适用于FAKE，那么您可能需要在FAKE github存储库上记录一个错误。谢谢！ – smoothdeveloper

我已经下载了一揽子贷款项目包正确执行的代码，改剧本是这样的：

#r @"./packages/FAKE/tools/FakeLib.dll" 
#r @"./packages/NuGet.Core/lib/net40-Client/NuGet.Core.dll" 

open System 
open System.Collections.Generic 
open System.IO 
open Fake 

Target "Test" (fun _ -> 
    printfn "==============================================================================" 
    global.NuGet.ZipPackage(@"Docker.DotNet.2.124.3.nupkg").GetFiles() |> Seq.iter(fun x -> printfn "%s" x.Path) 
) 

RunParameterTargetOrDefault "target" "test"

NuGet.Core的版本是2.12，我看到它是参考Mi未加载的crosoft.Web.Xdt。

也许你可以通过简单地使用paket并添加Docker.DotNet作为依赖来实现你想要的，它会为你提取它。

如果您有可复制的错误，请进行压缩并将问题发送到visualfsharp存储库。
