Code Coverage shows 0 even though dotCover reports are being provided

Hi ,
I want to use dotCover’s generated report to be imported by SonarQube for Code Coverage using TFS CI Pipeline.
I provided the parameter so that it will pick the report from the path and analyze it further to reflect in the Sonar Dashboard
I have included parameters in the Begin step like this -
begin /k:"$(ProjectName)" /"http://<ip>:9000/" /d:sonar.login="$(ProjectKey)" /d:sonar.verbose=true /d:sonar.cs.dotcover.reportsPaths="//abc/CodeCover/CodeCover.html"

When I run the Sonar-Runner it appears that it is parsing the dotcover reports and also says that Execution success but still the code coverage is showing 0% in the Sonar Dashboard .

Need help regarding how can I achieve code coverage after passing dotCover reports using TFS Pipeline ?

I got the solution , when using TFS Build just ensure that that the sonar build and dotCover report being generated are from the same machine . The file path should be completely in sync .

While implementing the whole process in any CI/CD Pipeline the most common failure reason can be related to this situation only - where we run sonar scanner on one machine and so code coverage using dotCover / (code coverage tool) in another machine. Neither it should be case where 2 almost similar branch are used to serve this purpose .

Its better to automate the whole process something like this -
Start SonarQube → Build Solution (main solution) → Generate dotCover → Sonar Build → End Solution

Hope this helps .
