c# Intellisense for unity 在 vscode 中不起作用

Question

我正在尝试让统一 Intellisense 在 vscode 中工作。 我正在使用：

- ubuntu 20.04
- unity 2020.3.23f1
- vscode 1.62.3 
- dotnet 6.0.100 
- mono 6.8.0.105

我在 vscode 中安装了 c# 扩展。

我设置： unity > 编辑 > 首选项 > 外部工具 > 外部脚本编辑器

到 /snap/bin/code 当我打开一个脚本时，它会在 vscode 中打开并给我这个：

        This project targets .NET version that requires reference assemblies that do not ship with OmniSharp out of the box (e.g. .NET Framework). The most common solution is to make sure Mono is installed on your machine (https://mono-project.com/download/) and that OmniSharp is started with that Mono installation (e.g. "omnisharp.useGlobalMono":"always" in C# Extension for VS Code).

当我将 omnisharp.useGlobalMono 设置为始终如其所说的那样时，我明白了：

我不知道这意味着什么或如何解决它，以便 Intellisense 能够正常工作。

Answer 1

尝试在External Tools 中单击regenerate project files。 ;)

我使用 vscode 和插件： https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.csharp https://marketplace.visualstudio.com/items?itemName=Unity.unity-debug

而且效果很好。
