错误CS0012：类型...在未引用的程序集中定义。您必须添加对程序集 'mscorlib, Version=2.0.5.0 的引用

Question

当我使用我的 StackExchange.Precompilation 分支构建代码时出现此错误 - https://github.com /MarkKharitonov/StackExchange.Precompilation

所以我接受了它（遵循https://stackoverflow.com/a/71611526/80002），将其调整为与最新版本的软件包配合使用它运行良好：

我对 Test.WebApp 做了一个小更改，但现在失败了：

更改是：

1. 将 NuGet 引用添加到 Common.Logging
2. 调用 ILog.Info

https://github.com/MarkKharitonov/StackExchange.Precompilation/commit/13a2c5f4a27915307d0a403d1c73f0922da87ebe

现在它失败并显示错误消息

C:\work\StackExchange.Precompilation\Test.WebApp\MvcApplication.cs(29,13): error CS0012: The type 'Action<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes'. [C:\work\StackExchange.Precompilation\Test.WebApp\Test.WebApp.csproj]

现在我明白 StackExchange.Precompilation 复制了以下逻辑7 年前的 csc.exe 代码。不幸的是，到目前为止，它是我必须替换 aspnet_compiler.exe 的最佳选择。

所以我的问题很简单 - 我们如何解决它？
