+      This intentionally does not reference 'xunit', 'xunit.core', or any runner packages.
+      XUnit recommends only using xunit.extensibility.*, xunit.assert, and xunit.abstractions for packages which "extend" xunit.
+      This allows consumers to decide which type of xunit runner they want to use to run these tests,
+      and avoids problems with `dotnet pack`.
