  ECHO But that ef.dll is tricky to find.
  ECHO.
  ECHO Be sure to tell the EF Core team how hard it is to deploy migrations via DLL.
  ECHO And let them know that it's mostly because it's impossible to find the ef.dll.
  ECHO It would be so much easier if we could just grab ef.dll during the build and
