.net - Powershell - 在应用程序配置文件中找不到程序集绑定(bind)重定向

Question

这里有问题...

我有一个 Powershell CmdLet，它在 32 位模式下运行时工作，在 64 位模式下失败。
问题是原因是什么以及如何解决。

情况

引用“OutlookHelper.Common.dll”的 Powershell CmdLet。最新版本是 2.0.0.0
CmdLet 还使用日志记录并引用“Logging.dll”。
Logging.dll 还引用了“OutlookHelper.Common.dll”，仅针对版本 1.0.0.0 编译。

我是如何使它工作的，这部分工作

在 Powershell 的应用程序配置文件中使用程序集绑定(bind)重定向:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true"> 
    <supportedRuntime version="v4.0.30319"/> 
    <supportedRuntime version="v2.0.50727"/> 
  </startup> 
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="OutlookHelper.Common" publicKeyToken="5e4553dc0df45306"/>
        <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

Powershell 32 位工作得很好

在 64 位机器上运行时，使用“Windows Powershell (x86)”可以正常工作。程序集管理器找到程序集绑定(bind)重定向:

Bind result: hr = 0x0. The operation completed successfully.

这就是麻烦开始的地方...

在 64 位机器上运行时，使用“Windows Powershell”它不起作用。程序集管理器未找到程序集绑定(bind)重定向:

当我让 Powershell 获取它自己的应用程序配置文件的内容时，我得到以下输出:

    </startup>

我试过的...

检查“特定版本”是否设置为“假”-> 是这种情况。

删除并重新添加了应用程序配置文件 -> 没有修复它。

从 SysWOW64 文件夹中的新应用程序配置文件开始 -> 没有修复它。

仔细检查加载的文件的内容(powershell.exe.Config 和 machine.config)-> 它们是相同的。

我猜

程序集管理器找不到程序集重定向绑定(bind)。

有什么解决办法吗？

为什么 64 位实例的 Fusion 日志没有提及“在应用程序配置文件中找到重定向:1.0.0.0 重定向到 2.0.0.0。”之类的内容？

这一切的原因是什么？

你能想出什么解决办法吗？

Answer 1

不是 100% 与 32/64 位问题相关，但是如果有人对 感兴趣工作程序集重定向解决方案请看这里Powershell config assembly redirect .

您可以使用 PowerShell 代码进行自定义程序集重定向，例如

$FSharpCore = [reflection.assembly]::LoadFrom($PSScriptRoot + "\bin\LIBRARY\FSharp.Core.dll") 

$OnAssemblyResolve = [System.ResolveEventHandler] {
  param($sender, $e)

  # from:FSharp.Core, Version=4.3.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
  # to:  FSharp.Core, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
  if ($e.Name -eq "FSharp.Core, Version=4.3.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a") { return $FSharpCore }

  foreach($a in [System.AppDomain]::CurrentDomain.GetAssemblies())
  {
    if ($a.FullName -eq $e.Name)
    {
      return $a
    }
  }
  return $null
}

[System.AppDomain]::CurrentDomain.add_AssemblyResolve($OnAssemblyResolve)

我首先加载 FSharp.Core 的正确版本从某个地方，因为 GAC 中的版本很旧(我想这也可能是你的情况)
