c# - 未找到框架“.NETFramework,Version=v4.7.1”的参考程序集
问题描述
我尝试在 Linux(Ubuntu 18.10)下使用 VSCode 打开 Unity3D 项目。omnisharp 扩展不加载项目,说没有找到程序集。
这似乎很愚蠢,但我还没有真正习惯.Net,而且我已经被这个错误困扰了好几天了。我一直在尝试重新安装 dotnet(甚至使用 snap 包)、mono、vscode 和omnisharp 扩展。
所以欢迎任何帮助!:)

解决方案
尝试了这里提到的步骤,没有解决错误。不得不将omnisharp.useGlobalMono
选项更改为always
. 这对C# extension for VS Code=1.23.2
.
资料来源:Reddit 邮报
您的错误输出告诉我您正在使用 VS Code 的官方 C# 扩展。所述扩展的最新版本 1.23.2 在其变更日志中有这样的说法:
For Mono-based development (e.g. Unity) that requires full .NET framework, you need to set "omnisharp.useGlobalMono": "always". This
在 Mono 升级其捆绑的 MSBuild 版本之前需要
默认设置 auto 不起作用。将其切换为始终并重新启动扩展程序。或者,您可以降级到 1.23.1。
