### Description

I have a mono-repo with a c# backend. I use Coverlet to generate a report. I’ve tried the following formats; json, lcov, opencover, cobertura. All result in 0% coverage when sent to Codecov. It does however show the graph of all files.

Hi @Fosol, I’m not too sure what’s happening here. I currently see coverage for files on your repository page [Codecov](https://codecov.io/gh/Fosol/PIMS).

I can see coverage for that particular commit being processed, but I don’t actually see the commit. Did you rebase or merge over it?

I ended up rebasing and attempting a number of other attempts to resolve. In the end it would appear we needed to use a different tool to generate the reports.

We were using Coverlet to generate our files. Locally we could see they had the relevant information, but uploading them to Codecov just didn’t work.

We are now going to try using the built in report generation with `dotnet`.

`dotnet test --collect:"XPlat Code Coverage" --settings coverlet.runsettings --no-restore`

With some configuration we believe this will work. Find out soon, as we’ll be merging into our repo and testing.

Sounds good, if you happen to have a copy of a coverlet report, I’d love to get that to my team to see if it’s supportable in the future.

Were you ever given this Tom, I’m trying to use Coverlet too but finding the same 0% coverage, I think I’ll try the built in donet report if thats what works

@clicketyclackety I don’t believe I was. If you have a setup, I can take a look to see if there’s just a problem with us parsing that kind of report. Do you have a commit SHA?

@clicketyclackety ahh, can you add the [GitHub app integration](https://github.com/apps/codecov) if you haven’t done so already?
