  1. \u00a0Ensure the ‘#include… generated.h’ line is the last of all includes.<\/strong>
    The line “#include xxxx.generated.h” has to be in your header file and the last of all includes.<\/p>

    \u00a0<\/p><\/li>

  2. Ensure the file name of the header and the suggested generated.h match.\u00a0<\/strong>

    In the line “#include xxxx.generated.h” ; xxxx has to match your header file name.eg Actor.h needs Actor.generated.h
    Resharper sometimes changes the file name when refactoring.

    <\/li>
