无法找到任何已安装的 .NET SDK

Question

我已经安装了多个版本的 .NET Sdk。现在 Omnisharp 建议无法正常工作。

输出显示这些

[info]: OmniSharp.MSBuild.ProjectManager
        Loading project: /BO-V2/Techne-Travel/travel-techne-bo-for-ota/src/Application/Application.csproj

但是 dotnet --info 显示了这个输出

  https://aka.ms/dotnet-download

哪个 dotnet 命令

/usr/bin/dotnet

我在谷歌中搜索并找到了这个 https://www.py4u.net/discuss/1941159。

我按照他们说的做了下面的事情。但我仍然面临同样的问题。为什么会出现这个问题？我该如何解决这个setting.json

{
    "editor.formatOnSave": false,
    "editor.codeActionsOnSave": {
        "source.fixAll": false
    },
    "omnisharp.path": "latest",
}

omn​​isharp.json

{
    "MsBuild": {
        "UseLegacySdkResolver": true
    }
}

全局.json

{
  "sdk": {
    "version": "6.0.101",
    "rollForward": "latestMinor"
  }
}

我应该怎么做才能使omnisharp正常工作？如果没有 Omnisharp 建议，我就无法继续工作。很难编码。请帮我。

请参阅此处的文档https://github.com/OmniSharp/omnisharp-vscode

使用 .NET 6 版本的 OmniSharp 从 C# 扩展版本 1.24.0 开始，现在可以选择使用在 .NET 6 SDK 上运行的 OmniSharp 版本。此构建需要安装 .NET 6 SDK，并且不使用 Visual Studio MSBuild 工具或 Mono。它仅支持可使用 dotnet build 构建的较新的 SDK 样式项目。不支持 Unity 项目和其他完整框架项目。

要使用 .NET 6 版本，请在 VS Code 设置中设置omnisharp.useModernNet为并重新启动 OmniSharp。true
