EnforceCodeStyleInBuild true does not fail the build when errors are present

Question

I'm using VS 2019 16.9.0 Preview 1.0 and have a project with the following PropertyGroup:

<PropertyGroup>
  <OutputType>Exe</OutputType>
  <TargetFramework>net5.0</TargetFramework>
  <LangVersion>latest</LangVersion>
  <EnforceCodeStyleInBuild>true</EnforceCodeStyleInBuild>
  <EnableNETAnalyzers>true</EnableNETAnalyzers>
</PropertyGroup>

In my .editorconfig file I created rules for fields to start with an underscore _. In Visual Studio I can see the error as IDE1006. However this does not cause the build to fail. From what I have read the setting <EnforceCodeStyleInBuild>true</EnforceCodeStyleInBuild> should cause the build to fail. I tested this in Visual Studio and from the Command Line using dotnet build.

How can I have this error to cause a build failure?

You have to set dotnet_diagnostic.IDE1006.severity = error or warning to get it work. CLI only recognize this syntax.
