 Best solution (to copy to .csproj file)
 - Runs after packing
 - RoboCopy needs space after path arg e.g "..\df sd " if path has spaces in it otherwise do not include space.
 - /XO ignores newer files in source
 - /NFL /NDL /NJH partially removes RoboCopy output
 - Since RoboCopy had different exit codes than MSBuild and many don't indicate error; need last two lines
 
  <Target Name="PostPack" AfterTargets="Pack">
    <Exec Command="
      set source=&quot;$(ProjectDir)$(OutDir).. &quot;&#xD;&#xA;
