Anyone in #dotnet land know how to persuade the dotnet/runtime build to emit code coverage?
Changing directory to the target test project (in this case System.Text.Json.Tests) and running
dotnet build /t:Test /p:Coverage=true /p:BuildTargetFramework=net10.0
did not seem to work; it spat out the coverage report, but there's no data (and it doesn't even include content at all for the JsonMarshal.* methods that are in the assembly, but not in the STJ namespace)
