SonarQube not showing test coverage net core azure

Hi Duncan,
Thank you for the reply, it set me in the right direction.
I got this fixed, the main problem was that dotnet test --collect "code coverage" was generating coverage report that contained just coverlet dll, no actual project dll.

coverlet.collector.dll
coverlet.core.dll

I tried to get this working in many ways, I still don’t understand why it works in a different project with same nuget versions and style of tests. in the end gave up and decided to use do this myself:

dotnet test PathTo.Tests.csproj --logger "trx;LogFileName=testresults.trx" /p:CollectCoverage=true "/p:CoverletOutputFormat=\"cobertura,opencover\""

Cobertura output is needed for VSTO, because it does not support opencover:

          - task: PublishCodeCoverageResults@1
            displayName: 'Publish coverage results'
            inputs:
              codeCoverageTool: 'cobertura'
              summaryFileLocation: 'pathToReports/coverage.cobertura.xml'

Opencover is needed for sonar cloud task SonarCloudPrepare@1:

 extraProperties:'sonar.cs.opencover.reportsPaths=$(workingDirectory)/LaunchBDataCollector.Unit.Tests/coverage.opencover.xml'

Last thing is to publish tests to VSTO:

          - task: PublishTestResults@2
            inputs:
              testRunner: VSTest
              testResultsFiles: '**/*.trx'
              failTaskOnFailedTests: true

Hope this is helpful for other people.
