vscode-csharp: connection to server is erroring

I meet the same problem.

dotnet --list-sdks
6.0.413 [/usr/local/share/dotnet/sdk]
7.0.304 [/usr/local/share/dotnet/sdk]

"dotnetAcquisitionExtension.existingDotnetPath": [
        {
            "extensionId": "ms-dotnettools.csharp",
            "path": "/usr/local/share/dotnet/dotnet"
        },
        {
            "extensionId": "ms-dotnettools.csdevkit",
            "path": "/usr/local/share/dotnet/dotnet"
        },
        {
            "extensionId":"ms-dotnettools.vscodeintellicode-csharp",
            "path":"/usr/local/share/dotnet/dotnet"
        }
    ]

I can’t fix it

I’ve been having a similar problem as @beta1scat… I have the newest version .net 7.0.306 downloaded, but perhaps it’s looking in the wrong location?

…And it repeats several times. Notably the Dotnet path /usr/bin/snap doesn’t match any of my paths that I’ve set up and doesn’t have a dotnet version when i navigated there and checked with? I’ve been trying to change the path by fiddling with it in settings, but nothing comes about…

@Neon-Cube mentioned setting the dotnet path in the settings, may I inquire which field that is specifically?? Here are my settings now:

{
    "omnisharp.monoPath": "/usr/bin/mono",
    "omnisharp.sdkIncludePrereleases": false,
    "omnisharp.sdkPath": "/snap/dotnet-sdk/216/sdk/7.0.306",
    "omnisharp.useModernNet": false,
    "dotnet.server.useOmnisharp": true,
    "omnisharp.dotNetCliPaths": [
        "/snap/bin/dotnet"
    ],
    "dotnet.defaultSolution": "/snap/bin/",
    "dotnet.unitTestDebuggingOptions": {

    },
    "dotnetAcquisitionExtension.existingDotnetPath": [
        "/snap/bin/dotnet"
    ]
}

Now I did check that snap/root has the correct version which is why I set it so. I’m a bit of a newbie so I do apologize if I mixed up any of the paths ^_^;

@beta1scat,

As @dibarbet said,

That’s fine - it means its running correctly - I need to add a log item here that indicates it is started because the current log is pretty misleading.

Thanks for your reply, I have already install dotnet 7.0, but when I open vscode, it also Dowloading the .NET Runtime. Should I set up something else?

To confirm, do you still have the dotnetAcquisitionExtension.existingDotnetPath in your settings pointing to /usr/share/dotnet?
