    I found a way around this issue (for me). I'm not using any networking so I just double clicked on each of the errors and commented out the offending lines (and one time the if statement above). This allows my project to compile.

    This error is in some deprecated code, if your project is using it then it will be going away in the future and then you will have bigger issues. If your project is not using networking then its probably safe to do my above work around.
