Selenium Test .net core 3.1 on Release Pipeline has framework Mismatch

Question

I have a simple selenium test on .net core 3.1 with selenium.webdriver.

I build it on the build pipelines with yaml that does Restore > publish > publish artifact. The Dlls look fine. I put this into a release pipeline and I keep getting:

My pipeline tasks are a Pipeline Platform installer running the Latest and a VSTest task that runs the "Installed by tooler". My Agent is Azure pipelines with windows-2019. Not sure what I am missing here. I cant run this simple test. Thanks

If you using VStest task to run dotnet-core-3.1 tests. You need to specify the framework option to .NETCoreApp,Version=v3.1 in the Other console options field: See below:

- task: VSTest@2
  displayName: 'VsTest - testAssemblies'
  inputs:
    testAssemblyVer2: |
     **\*Test*.dll
     !**\*TestAdapter.dll
     !**\obj\**
    codeCoverageEnabled: true
    otherConsoleOptions: '/framework:".NETCoreApp,Version=v3.1"'

You can also use dotnet test task in the release pipeline to run the tests on .net core 3.1.
