coverlet.msbuild 2.8.0 does not combine coverage when using MergeWith

See original GitHub issue

Dependabot pushed a number of updates to coverlet.msbuild to repositories I maintain just now to bump from 2.7.0 to 2.8.0, and for projects where code coverage is aggregated together using the MergeWith MSBuild property, the stats are no longer being combined.

Here’s such an example PR: https://github.com/justeat/httpclient-interception/pull/171

This is causing builds to fail as their minimum coverage level specified by the Threshold MSBuild property is now no longer being met.

I know that @danielpalme reportgenerator can picks more than one reports coverage file and generate one final html(or other types) report, I use it and AFAIK it’s used also by official azure dev ops, so it’s stable(Daniel can you confirm?). https://github.com/danielpalme/ReportGenerator#usage--command-line-parameters

Yes Azure DevOps also uses ReportGenerator internally to generate the coverage report.
Merging several files was always supported by ReportGenerator. You can give it a try.

And thanks for the advice we’ll keep more attention on versioning (related to missing breaking behavior)!
