"Coverlet.MSbuild.Tasks.CoverageResultTask" task was not given a value for the required parameter "InstrumenterState"

Hello,

I have setup a post build event in my shared test library, this library has not tests but is referenced by all my test projects, I did this because I want to automatically generate the reports every-time the projects are built.

  <Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <Exec Command="cd $(SolutionDir)&#xD;&#xA;dotnet test" />
  </Target>

however I am getting the following error when I try to build the solution and the build hangs:

C:\...\packages\coverlet.msbuild\2.6.2\build\coverlet.msbuild.targets(41,5): error MSB4044: The "Coverlet.MSbuild.Tasks.CoverageResultTask" task was not given a value for the required parameter "InstrumenterState".

for the record, I’ve faced the same error, and I’ve realized that I’ve had added coverlet nuget to business projects. When I removed it, it’s been fixed.

in my case after getting that error, I’ve installed MS.Net.Test.Sdk which cleared the error so in my test project package I do have coverlet.msbuild version=“2.6.3” Microsoft.NET.Test.Sdk version=“16.2.0” Microsoft.CodeCoverage version=“16.2.0” — which a dependency of Sdk
