For anyone encountered the same problem, I found a temporary solution.

Add omnisharp.json in your project folder with:

{
  "MsBuild": {
    "MsBuildSDKsPath": "/usr/local/share/dotnet/sdk/2.2.103/Sdks",
    "UseLegacySdkResolver": true
  }
}

Where .../sdk/[version]/... the version part in MsBuildSDKsPath should point to the version you desire.

Hope it works for you.

Seems like a duplicate of #1416.

I tried updating to latest roslyn release, and use the suggestion above for omnisharp.json. While it no longer complains about not finding the sdk, vscode complains about everything, from using System to a simple void.

Here I am running Linux Mint, and dotnet 2.1.602. Happy to help with the debug.

[sharkAndshark]

@afterwind-io it works :)

[ambs]

dot net update to 2.1.603, still same problem.

[egel]

Today I stumble upon the same error. Installing the dotnet through the official mac installer solve the problem for me. Using SDK v3.1.4.
