which dotnet command

/usr/bin/dotnet

I have searched in google and find this https://www.py4u.net/discuss/1941159.

I did below as they said. But Still I face the same issue. Why this issue? How can I solve this setting.json

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

omnisharp.json

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

global.json

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

What should I do to make omnisharp works fine? I could not continue the work without Omnisharp Suggestion. It is hard to code. Please help me.

See the documentation here https://github.com/OmniSharp/omnisharp-vscode

Using .NET 6 builds of OmniSharp Starting with C# extension version 1.24.0, there is now an option to use build of OmniSharp that runs on the .NET 6 SDK. This build requires that the .NET 6 SDK be installed and does not use Visual Studio MSBuild tools or Mono. It only supports newer SDK-style projects that are buildable with dotnet build. Unity projects and other Full Framework projects are not supported.

To use the .NET 6 build, set omnisharp.useModernNet to true in your VS Code settings and restart OmniSharp.
