How about using dedicated .runsetting for Visual Studio environment by using BuildingInsideVisualStudio MSBuild property?

  <PropertyGroup Condition="'$(BuildingInsideVisualStudio)' == 'true'">
    <RunSettingsFilePath>$(MSBuildProjectDirectory)\VisualStudio.runsettings</RunSettingsFilePath>
  </PropertyGroup>

Note:
When using xUnit.v3 package.
It need to specify following settings to disable MTP and use VSTest.
<DisableTestingPlatformServerCapability>true</DisableTestingPlatformServerCapability>

We don't do anything with this setting (I've never even heard of it), so my guess is this is probably a question for the VSTest team rather than us.

Good idea, @filzrev , i'll give it a go.
@bradwilson , got it. so is it fair to say there's no way to customize logger for visualstudio.xunit (apart from runsettings)?

P. S. VSTestLogger seems to fairly used (according to my github code search), and since this package is a vstest adapter for xunit, i was assuming it'll be supported. Clearly the wrong assumption, thanks for clarifying

I don't believe it has ever been our responsibility to read and respect that value. The logger in VSTest has nothing to do with us.
