c# - 从 .Net Core 运行 Powershell - 无法加载文件或程序集 Microsoft.Management.Infrastruct

Question

我一直在尝试使用以下代码从 .Net Core Web 应用程序运行 powershell 脚本(此处不讨论最佳实践;)):

    string command = @"& """c:\\my Folder\\myScript.ps1""";

    using (var ps = PowerShell.Create())
    {
        var results = ps.AddScript(command).Invoke();
    }

它在我的开发机器上运行良好，但在生产中尝试执行此函数时失败:

ps.AddScript(command).Invoke()

我收到以下异常:

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Management.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

我不知道应该安装哪个框架/包才能运行。目标框架是已安装的.Net Core 2.1，因此除了上面提到的行之外，应用程序运行良好。

deps.json 文件包含以下内容:

    "Microsoft.Management.Infrastructure/1.0.0": {
        "dependencies": {
          "NETStandard.Library": "2.0.3",
          "System.Runtime.CompilerServices.VisualC": "4.3.0",
          "System.Runtime.Serialization.Xml": "4.3.0",
          "System.Security.SecureString": "4.3.0",
          "System.Threading.ThreadPool": "4.3.0"
        },
        "compile": {
          "ref/netstandard1.6/Microsoft.Management.Infrastructure.Native.dll": {},
          "ref/netstandard1.6/Microsoft.Management.Infrastructure.dll": {}
        }
      }

已安装的 Nuget 软件包:

Microsoft.AspNetCore.App (2.1.1)
Microsoft.PowerShell.Commands.Diagnostics (6.0.5)
Microsoft.PowerShell.SDK (6.0.5)
Microsoft.PowerShell.WSMan.Management (6.0.5)

编辑 我还添加了 Microsoft.Management.Infrastruct (1.0.0)但这并没有解决问题

编辑2 Dev 是 Windows 10 Pro，Prod 是 Windows Server 2016 Standard

编辑3 当直接通过 PowerShell 启动时，该脚本在产品上运行良好。当 Web 应用尝试运行 PowerShell 时显示错误。

编辑4 应用程序池帐户具有管理员权限，并且与我用于手动运行脚本的帐户相同(不是很好的做法，但现在我只是尝试运行此脚本)。

编辑5 我尝试将dll放在服务器上应用程序的文件夹中，然后重新启动站点+回收应用程序池。我尝试了在开发机器上可以找到的每个版本，但没有任何效果:/

编辑6 将 nuget 包从 6.0.5 更新到最新的 6.2.1，同样的问题

Answer 1

我遇到了同样的问题，Microsoft.Management.Infrastruct.dll(及相关文件)未发布。通过指定 non-portable RID 来解决在发布配置文件中(*.pubxml，不是 *.csproj):

<RuntimeIdentifier>win7-x64</RuntimeIdentifier>

问题可能是由于以下事实引起的:C:\Users\UserName\.nuget\packages\microsoft.management.infrastruct\1.0.0\runtimes 下只有包含非可移植 RID；没有 win-x86 和 win-x64。
