Unity 文件加载失败：“System.Threading.Tasks.Dataflow”

【中文标题】Unity 文件加载失败：“System.Threading.Tasks.Dataflow”

【英文标题】：Unity file failed to load: "System.Threading.Tasks.Dataflow"

【问题描述】：

这周我偶然遇到了一个阻止我继续工作的错误，我不知道如何解决它。我为一个 Unity 项目使用 VS Code，它告诉我

OmniSharp.MSBuild.ProjectManager
Attempted to update project that is not loaded: c:\Users\jamie\Documents\Unity\Projects\OTHERWOODLY\Assembly-CSharp.csproj

问题是由错误日志中的这一行引起的，但我也会在帖子末尾发布整个错误：

System.IO.FileNotFoundException: Could not load file or assembly 'System.Threading.Tasks.Dataflow, Version=4.6.3.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

我已尝试更新 .NET 并重新下载了最新版本的 Mono。我还在 VS Code 中将这些设置添加到我的 C# 设置中

   "omnisharp.path": "latest",
   "omnisharp.useGlobalMono": "always",

似乎没有什么可以解决它。在这里真的很茫然，如果有人有任何想法，我将不胜感激！

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

【问题讨论】：

这与Could not load file or assembly 'System.Threading.Tasks.Dataflow, Version=4.6.3.0有关吗（4小时前问）？

@derHugo 看起来像，虽然发布的初始解决方案并没有为我解决。我没有 Visual Studio 社区或构建工具，我已将 VS Code 更新到最新版本。该错误仍然存​​在。

【参考方案1】：

我相信我遇到了同样的问题，并通过下载 Visual Studio Build Tools 2019 https://visualstudio.microsoft.com/visual-cpp-build-tools/ 解决了它，然后用它来安装“.NET 桌面构建工具”。我没有包括任何可选选项。 然后我重新启动了VS Code，错误就消失了。
