When I run the sonar analysis on PR’s I see the following message in the coverage section of the Sonar report:  
A few extra steps are needed for SonarCloud to analyze your code coverage  
[Setup coverage analysis](https://docs.sonarsource.com/sonarcloud/enriching/test-coverage/overview/)

I think that I have completed all of the steps in the link. What am I missing?

Here is my ymal file:

When I change code that I have covered with a test, it shows 0 lines covered.

The above will not work without Visual Studio Enterprise addition. So, I switch to using Opencover and it worked great. I followed [.NET Core Code Coverage done right – writeabout.net](https://writeabout.net/2019/04/27/net-core-code-coverage-done-right/) and modified its yml to work on my solution. This allow me to get coverage reports in Both Azure Dev opts and Sonar. Here is my yml:

# Build and test ASP.NET Core projects targeting the full .NET Framework.
