Dotnet test coverage always null

Question

I have an issue with test coverage. When I run this command

dotnet test ../XZrcndee.sln --output ../coverage /p:CollectCoverage=true /p:CoverletOutput=results\coverage /p:CoverletOutput=..\results\coverage /p:MergeWith=..\results\coverage.json /p:CoverletOutputFormat="opencover"

It show me that codecoverage is 0

When I try run dotnet test in only one project I got the correct result.

dotnet test ../XZrcndee.Domain.Tests/XZrcndee.Domain.Tests.csproj --output ../coverage /p:CollectCoverage=true /p:CoverletOutput=results\coverage /p:CoverletOutput=..\results\coverage /p:MergeWith=..\results\coverage.json /p:CoverletOutputFormat="opencover"

Do I miss somthing?

Kind Regards

Try this

dotnet test ../XZrcndee.sln --output ../coverage /p:CollectCoverage=true /p:CoverletOutput=results\coverage /p:CoverletOutput=..\results\coverage /p:MergeWith=..\results\coverage.json /p:CoverletOutputFormat="opencover" /maxcpucount:1

make sure to cleanup the "coverage.json" after each run otherwise it will merge results from mulitple runs also.
