I'm trying to get into understanding quasar source code (R.A.T) on Github
It's an Advanced Communication between Server/Client using Commands.
The interesting part which I didn't really understand is the Class Builder
which uses The Mono.cecil Reference to modify Assembly Variables's values that they were Empty such as Host, Port etc...
Solved by asking the project owner about the Client.bin file and was about the Mono.cecil reference can be found here
and i got some examples on how to use there
