Omnisharp C# 无法在带有 Unity 的 Ubuntu 22.04 上运行

Question

由于 Windows 每天给我带来新的问题，我永久地转向 Linux（Kubuntu 22.04 LTS）。 但是在使用 Unity Editor 时，VS Code 并没有为我提供 Intellisense。

在我的系统中： mono-complete dotnet-sdk-6.0 && aspnetcore-runtime-6.0包

在 VS Code 中：安装了“C# 扩展”

案例一：-

omn​​isharp.useModernNet: false

任何修复？ 谢谢

好的，我已经解决了这个问题。

我所做的是删除dotnet （sdk 和运行时）的 Microsoft 包并安装 snap 版本。

而且我还完全删除了mono-complete并再次安装它，瞧！ 现在可以用了谢谢
