OmniSharp isn't picking up FxCop Analyzer settings in top-level .editorconfig

[alexrp]

(VS Code 1.44.0 / OmniSharp 1.34.15)

In my top-level .editorconfig, I have:

[*.cs]
dotnet_diagnostic.ca2007.severity = none

And in my ´omnisharp.json`:

{
  "FormattingOptions": {
    "EnableEditorConfigSupport": true
  },
  "RoslynExtensionsOptions": {
    "EnableAnalyzersSupport": true
  }
}

When I run dotnet build, CA2007 is indeed disabled as expected. However, in VS Code, I still see CA2007 warnings. I'm not sure whether this is a bug or I'm just doing something wrong.

There is no support for that at the moment.
It's already tracked in a separate issue though #1657 (comment)

Is there at least a way to disable analyzers pulled in from NuGet?

As it stands, EnableAnalyzersSupport=false seems to disable absolutely everything, including IDE* analyzers. But setting EnableAnalyzersSupport=true is near-unusable due to all the false positives that show up due to OmniSharp not picking up .editorconfig for analyzers from NuGet.

yes, you can create a ruleset file
