Question

关于此错误，有许多类似的帖子，很遗憾，它们都没有帮助。

我已将解决方案项目升级到.NET 4.8，然后发布了command to retarget nuget packages：

update-package -reinstall -ignoreDependencies

此后，单元测试失败并显示错误：

消息：System.IO.FileNotFoundException：无法加载文件或程序集'System.Runtime.InteropServices.RuntimeInformation，版本= 4.0.2.0，文化=中性，PublicKeyToken = b03f5f7f11d50a3a'或它的依赖项之一。该系统找不到指定的文件。 ---- System.IO.FileNotFoundException：无法加载文件或程序集'System.Runtime.InteropServices.RuntimeInformation，Version = 4.0.0.0，文化=中性，PublicKeyToken = b03f5f7f11d50a3a'或其中之一依赖性。系统找不到指定的文件

融合日志输出如下：

我尝试了一些建议的东西

Update app.config, add binding redirects
Update System.Runtime.InteropServices.RuntimeInformation v4.3.0 & ystem.Runtime.InteropServices v4.3.0在所有直接或间接引用MongoDB的项目中。
Add System.Runtime & System.Runtime.InteropServices.RuntimeInformation binding redirects

从Fusion日志来看，它会查找GAC，但找不到程序集（我可以确认v。4.0.2.0位于GAC_MSIL中）。

如何摆脱这个错误？

Answer 1

我遇到了同样的问题，CAD bloke's answer 向 a similar question 提供了对我有用的解决方案：

具体来说，我必须从我的项目中删除 System.Runtime.InteropServices.RuntimeInformation NuGet 包。事实证明，它包含在 .Net >= 4.71 中，因此无需显式添加包。

Answer 2

当我在Windows服务器上运行我的项目时，我遇到了同样的问题，但它给出了一个错误。

Could not load file or assembly 'System.Runtime.InteropServices.RuntimeInformation, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

然后两天后搜索此内容。我通过添加

解决了这个问题

System.Runtime.InteropServices.RuntimeInformation.dll

在我的项目bin文件夹中下载 here file

Answer 3

我有类似的项目设置，并且遇到了如上所述的类似问题（单元测试因类似错误而失败）。 NuGet包结构已针对System.Runtime.InteropServies.RuntimeInformation v4.3.0进行了更改。我没有在项目中升级此NuGet软件包，而是升级了项目中所有其他软件包。此后，我所有的单元测试都成功通过了。

我不建议您这样做，但是如果有时间限制，这种方法很有用。

nuget包重新定向后无法加载文件或程序集'System.Runtime.InteropServices.RuntimeInformation'
