这里有个问题...
我有一个 Powershell CmdLet,在32位模式下运行正常,但在64位模式下会失败。 问题是原因是什么以及如何解决。
情况
Powershell CmdLet 引用了 'OutlookHelper.Common.dll'。最新版本为2.0.0.0。
CmdLet 还使用了记录日志并引用了 'Logging.dll'。
Logging.dll 也引用了 'OutlookHelper.Common.dll',但只编译为1.0.0.0版本。
我是如何部分解决的
在 Powershell 应用配置文件中使用程序集绑定重定向:
<?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位运行良好
在64位计算机上运行时,使用“Windows Powershell(x86)”可以正常工作。程序集管理器会找到程序集绑定重定向:

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

问题从这里开始...
在64位机器上,使用“Windows Powershell”不起作用。程序集管理器无法找到程序集绑定重定向:

当我让PowerShell获取其自己应用程序配置文件的内容时,我会得到以下输出:

我尝试过的...
- 检查是否将“Specific Version”设置为“false”->是这种情况。
- 删除并重新添加应用程序配置文件->未修复。
- 在SysWOW64文件夹中使用新的应用程序配置文件启动->未修复。
- 仔细检查已加载的文件内容(powershell.exe.Config和machine.config)->它们是相同的。
我的猜测
- 程序集管理器无法找到程序集重定向绑定。
有什么解决方案吗?
- 为什么64位实例的融合日志没有提到类似“在应用程序配置文件中发现重定向:1.0.0.0 重定向到2.0.0.0。”这样的内容?
- 所有这些的原因可能是什么?
- 您能想到任何解决方案吗?
