Visual studio code VSCode可以'；t仅在安装C#扩展时检测安装

我的版本是1.24.1。我尝试过的其他扩展的每一次安装都有效

当我尝试为VisualStudio安装“C”时，出现错误“安装'ms vscode.csharp'失败”

然后我尝试手动安装vsix文件，我得到了这个错误

This extension is not installable on any currently installed products

我已尝试重新安装扩展，重新安装VScode，然后重新启动。
我不支持代理或vpn

错误似乎是它无法检测visual studio代码，即使它确实已安装。这是安装C#扩展所独有的。

似乎检测到Visual Studio（社区版），但不是.Net核心

如“”所示，在安装该扩展之前，请确保已首先安装
