UDP Send and receive

So i’ve been trying to follow the Rama tutorial here: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums
But am having no luck when i try to build the c++ files in visual studio community 2015.

Does anyone have any advice? Is this tutorial out of date and as such not going to work in the latest version of the engine. I’m just trying to create a simple send and receive setup. Help/advice/ideas really really appreciated.

Thanks all
