Thanks @MarcoRossignoli. I totally see that this fixes the issue. But why doesn't this happen with v1.3. There we already had the target CopyCoverletDataCollectorFiles? Also I don't really get why CopyCoverletDataCollectorFiles is needed at all? I would assume that nuget copies the resolved files by its own. E.g. in coverlet.msbuild.targets we don't have something like this target and the files are copied nevertheless.

I haven't find a chance to look at this yet, I'll do it on this weekend. :)

@daveMueller this scenario should run only when we publish so with dotnet publish and after a user can run test/coverage with dotnet test file.dll in all other cases coverlet is resolved using nuget folder.

But why doesn't this happen with v1.3. There we already had the target CopyCoverletDataCollectorFiles?

didn't check, but looking with binlog should be easy to understand.
