Networking Programming Over LAN in UWP

Question

I am trying to make 2 different applications on different 2 computers respectively. Moreover i want these applications to communicate over ethernet cable. Let these two apps from two different computers be A & B.

Firstly I want to check the connect both apps, secondly both apps should display network status and last is that I want to send "Hello world" from app A & to receive it on app B.

 

I am trying it for a week but, unable to do so. I have seen enough links and videos but didn't get for which i am looking for & all that stuff was difficult. from some websites a just didn't found code for both A & B app.

 

Going through too much stuff i am confused that what should i use and how, these terms include "Tcpclient, Tcplisenter & Sockets". This why i am not uploading my code as it is too much messed up with these concepts.

 

Kindly guide me to accomplish my task, It will be so nice of you.
