[Update doc only new SDK style supported]error MSB4044: The "Coverlet.MSbuild.Tasks.CoverageResultTask" task was not given a value for the required parameter "InstrumenterState".

Hello GitHubFamily,

I m trying to use publish code coverage for Nunit test. I have created my pipeline from Azure DevOps and utilizing .Net Core (test) task to execute unit test cases and publish code coverage. However, I am getting above mentioned error.

So what all I have done: A unit test project in VS 2019. Few sample unit test. From Manage Nuget, got Nunit, Nunit test adapter and code coverage tool - coverlet.msbuild

Reference screenshot:

Below is the pipeline I am using:

I had below package.config after installing the nuget component. However, as I received an error I carried out certain modifications in the hope to fix the issue. The comment code was by default and the uncommented one is modified one.

I am not using, however, putting YAML for .NET Core (test) if that helps: steps:

• task: DotNetCoreCLI@2 displayName: ‘Test copy’ inputs: command: test projects: ‘D:\CurrentUnitTestAgent_WorkingFolder**\CodeCoverageScenario\CodeCoverageScenario.sln’ arguments: ‘/p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:CoverletOutput=$(Build.SourcesDirectory)/TestResults/Coverage/’ condition: succeededOrFailed()

Hello Marco,

Thank you for all the help.

Yes, for the new projects (NET Core) with SDK it works fine. Let me try to update my existing test project (.NET Framework) to have a new style SDK. Let me see how the project could be updated to have the new SDK style. I would try to update the project and let you know.

I appreciate all the help.

Thank you.
