我正在尝试使用 Unity 自动完成，但我不断收到此消息：

我不太确定发生了什么，但我也安装了 Visual Studio，但作为解决方案也失败了。

我遇到了同样的问题，我从这个 reddit post 得到了这个： https://www.reddit.com/r/vscode/comments/ooyijp/issue_with_omnisharpc_extension/

“您需要告诉 VS Code 仅使用 omnisharp 附带的捆绑 MSBuild 版本。每 https://github.com/OmniSharp/omnisharp-vscode/issues/4358

您可以使用以下内容将 omnisharp.json 添加到工作空间的根目录中

{ "msbuild": { "useBundledOnly": true } }

对于全局效果，文件可以放入 %USERPROFILE%/.omnisharp/
