这周我偶然遇到了一个bug，它阻止了我继续工作，我不知道如何解决它。我打开一个Unity项目的VS Code，它告诉我
OmniSharp.MSBuild.ProjectManager
Attempted to update project that is not loaded: c:UsersjamieDocumentsUnityProjectsOTHERWOODLYAssembly-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.
我已经尝试更新。net并重新下载了Mono的最新版本。我还将这些设置添加到VS Code
中的c#设置中。"omnisharp.path": "latest",
"omnisharp.useGlobalMono": "always",
似乎没有什么能解决它。这里真的很茫然，如果有人有任何想法，我将非常感激!

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!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 [HKLMSoftwareMicrosoftFusion!EnableLog].
我相信我也有同样的问题，并通过下载Visual Studio Build Tools 2019 https://visualstudio.microsoft.com/visual-cpp-build-tools/解决了这个问题，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VS Code，错误消失了。
