VS 2026 Net 10 can't get coverlet coverage xml files

[mdelgadov]

Maybe I'm too early to the party, but in VS 2026 insiders, using Coverlet.collector 6.0.4, this instruction (and others) do not work:

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:CoverletOutput=../Test Results/coverage.xml

Couldn't find any issues open, and I'm new at coverage issues, so any hint will be greatly appreciated.
