you have to activate the dotnet-script compatible mode in OmniSharp as it defaults to CSI mode (no nuget support). you need to add omnisharp.json file at the root of your workspace. you can also add it globally using these instructions https://github.com/OmniSharp/omnisharp-roslyn/wiki/Configuration-Options#global-omnisharpjson

{
  "script": {
    "enableScriptNuGetReferences": true,
    "defaultTargetFramework": "netcoreapp3.1"
  }
}

dotnet script init also generates the relevant omnisharp.json

OK let’s close this one then - thanks
