UE4Editor-Gamename.dll needs to be compiled.

So i just created a C++ Class so as to get target.cs because i wanted to check out SteamMultiplayer. I used RAMA’s Guide. but it is giving me this weird error at the start " UE4Editor-Gamename.dll needs to be compiled." And when i allow it to compile it gives the source needs to be compiled manually it was asking me to get toolchain for vs2017/18 which i did get but the thing is i dont think so it even created the .dll file.
