Build machine needs to install a 10.0 runtime. You can do this with an update to global.json. I can fix it.

[ericstj]

You may still need the 8.0 runtime if your tests target 8.0 as well. Update: maybe they don't since it looks like they target NetMinimum. https://github.com/search?q=repo%3Adotnet%2Fcommand-line-api+TargetFramework+path%3A**%2F*test*csproj&type=code
