c# - 使用单声道时缺少 Microsoft.Extensions.DependencyInjection 的 System.Collection 依赖项

Question

我正在处理一个相当复杂的项目，它有很多依赖项。在我使用旧 Mono（来自 Xamarin 的 4.8，遗憾的是当时无法升级）的 Debian 9 安装中，当我尝试运行我的应用程序的可执行文件时，我收到以下错误（我已排除与问题）：

Mono: Assembly Loader probing location: '/home/test/Application/Microsoft.Extensions.DependencyInjection.Abstractions.dll'.

The assembly was not found in the Global Assembly Cache, a path listed in the MONO_PATH environment variable, or in the location of the executing assembly (/home/test/Application/).

Mono: Failed to load assembly Microsoft.Extensions.DependencyInjection[0xa3d0f58]


Unhandled Exception:
System.TypeLoadException: Could not load type 'Microsoft.Extensions.DependencyInjection.ServiceCollection' from assembly 'Microsoft.Extensions.DependencyInjection, Version=1.1.1.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.
[ERROR] FATAL UNHANDLED EXCEPTION: System.TypeLoadException: Could not load type 'Microsoft.Extensions.DependencyInjection.ServiceCollection' from assembly 'Microsoft.Extensions.DependencyInjection, Version=1.1.1.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

我通过使用以下命令运行我的应用程序来获得此输出

MONO_LOG_LEVEL=debug MONO_LOG_MASK=asm mono Application.exe

我看到的是程序集加载器正在尝试加载 DependencyInjection，它也存在于我的可执行文件所在的目录中。使用dotPeek我反汇编了Microsoft.Extension.DependencyInjection.dll并且确实System.Collection存在：

我查看/usr/lib了内部（包括mono文件夹），但找不到任何System.Collections.dll，顺便说一句，Windows 上存在该应用程序，并且该应用程序在那里运行得很好。

我试图寻找所有 Xamarin 软件包，但由于版本的年龄以及 Xamarin 确保在他们的存储库中不容易找到它，这被证明是相当棘手的。作为解决方案一部分的所有项目都以 .NET 4.5.1 为目标。

我将尝试复制 Windows 版本并希望它可以工作，但我仍然感到惊讶的是，没有找到基本的东西。
