Directory.Build.targets

<Project>

  <!--
    Note: The following platform-specific properties need to be set in both Directory.Build.props and DirectoryBuild.targets.
    TODO: Figure out how to consolidate to a single location.
    - Directory.Build.props will get imported at the beginning of the project files, so sets properties that are
    prerequisites for the build and can be overriden in the project files.
    - Directory.Build.targets will get imported at the end of the project files, so can be used to run common custom
    tasks or ultimately override properties set in Directory.Build.props or the project files.
