  <!-- Settings that can only be decided AFTER a project has said what it is. Directory.Build.props is
       imported before the project body, where <IsTestProject> has not been written yet, so anything
       keyed on it has to live here: this file is imported afterwards. -->

  <!-- The trim/AOT rules of PRD §2 apply to shipping code. Test and benchmark projects run on the
       full runtime, reference test frameworks that are built on reflection by design, and are never
       published — holding them to the analyzer would produce a wall of warnings that says nothing
       about the product and would train everyone to ignore the ones that do. -->
