c# - 通过 Unity 启动时，Visual Studio Code .NET 框架无法工作

Question

我无法让 .net 框架在 vscode 中运行。当我正常打开vscode时，.net框架可以正常运行。但是，当我在 unity 中打开 .cs 文件并使用 vscode 作为默认编辑器时，我会收到错误消息，因为 .net 框架不再在 vscode 中运行。我需要 C# 特定自动完成和语法错误的框架。我收到了另一篇已关闭的帖子的评论，说我需要更具体地说明这个问题。这不是 Unity 不支持 .net 框架的问题。我尝试过重新启动电脑、重新启动 vscode、重新启动 unity、重新导入 unity 包以及重新下载 .net 框架。无论 vscode 是否使用 Unity 快捷方式启动，所有 C# 代码都可以在 Unity 内部和外部正常运行，但运行 dotnet 命令和任何与 C# 相关的自动完成/语法不起作用。我可以通过在没有 Unity 的情况下运行 vscode 并导航到该文件来从 Unity 编辑 C# 代码。感谢您的帮助。

unity启动的vscode中运行dotnet命令

在通过快捷方式启动的 vscode 中运行 dotnet 命令

在 Unity 中工作的 C# 代码

答案在日志中:

.Net sdk/系统库是通过 Visual Studio 安装的，因此 vscode/omnisharp 尝试从 Visual Studio Community 16.6 安装中提取它们(相关信息位于日志的开头)。但 VSCommunity 似乎没有安装 v4.7.1 目标包。

要解决此问题，请访问:

Visual Studio Installer -> Visual Studio Community -> More -> Modify -> Individual Components

并检查“.NETFramework v4.7.1”包。安装完毕后，重新启动，就可以开始了。
