C# Unity项目与VSCode集成时出错

我正在尝试使用Unity2020.1.9f版本开发我的第一个游戏。由于配置较低，我使用VSCode作为编辑器，而不是默认的Visual Studio。但每次我在VSCode中打开项目时，都会显示导入错误 Mirrorpackage用于多人游戏功能。我认为我已正确导入它，因为该项目在Unity中运行良好。但由于此错误，我无法在VSCode中使用Intellisense for Mirror package。 这是错误的外观：

这是在VSCode中打开项目时的Omnisharp日志

以前在导入UnityEngine.UI时也发生过同样的问题，但在我重新生成csproj文件时解决了。但当前的导入没有解决。我尝试了从降级C扩展到重新安装Unity的所有方法，但都没有效果。请帮助。提前感谢您解决此问题，您应该转到unity软件包管理器并将Visual Studio代码编辑器更新为1.2.3版

使用Unity 2019.4.1f1 LTS测试要解决此问题，您应该转到Unity软件包管理器并将Visual Studio代码编辑器更新为1.2.3版

使用Unity 2019.4.1f1 LTS进行测试
