Upgrade to version 3.0.0/3.1.0 causes FileNotFoundException (Newtonsoft assembly)

Hi,

At first I thought this is APM package that is causing this issue but after upgrading/downgrading different packages for a day I found out that it is coverlet.collector that is causing it. The issue only shows up in docker container though, we’re using mcr.microsoft.com/dotnet/sdk:5.0-alpine image.

I solved my problem by adding IsPublishable=false in csproj of test projects (instead of removing the test dlls in CI/CD before building final docker image with dlls).

As for running dotnet test ..., this has never been a problem.

I still think coverlet shouldn’t add a Newtonsoft dll directly instead of relying on nuget dependencies, but personally I’m not having problems anymore with that since using IsPublishable=false like stated above.

I believe the issue is coverlet.collector nuget package doesn’t specify dependencies, but still includes Newtonsoft.Json.dll.

From the detailed output publish, I see this :

Copying file from "/home/--ME--/.nuget/packages/coverlet.collector/3.0.1/build/netstandard1.0/Newtonsoft.Json.dll" to "/home/local/--ME--/dev/projects/Xxx/tests/Xxx.Tests.Lib/bin/Release/net5.0/publish/Newtonsoft.Json.dll".
