EOS Setup for 5.2

Hello Community, currently I am building a project on 5.2 and want to integrate EOS. I’ve seen many tutorials but these were not for 5.2 and always fail at certain points. I have already implement all keys (ID, numbers, etc) but I fail in Visual Studio at Login, create/join Session etc. Is there a Tutorial out for 5.2 that someone can provide that works before I Invest again so much time and fail at some point because of something invalid (I am not very good in C). Replication is fine, all works when testing as Client.

Many Thanks.
