Screenshots: From one of my older posts, but you can't really "screenshot" this anyways.
Oxidizer is an Assembly-CSharp.dll loader for the Steam version of Rust. This will let you do Assembly-CSharp.dll mods like before.
RustStripper will dump all the needed assemblies to mod Assembly-CSharp.dll.
RustStripper:
Create a directory in the Rust directory called "dump"
Run RustStripper.exe
Run Rust through Steam
If a message box pops up and says "Dump Complete" then it worked. If it didn't try again.
All the files related to Assembly-CSharp.dll are in dump/
Oxidizer:
Create a directory in the Rust directory called "ox"
Put your modded Assembly-CSharp.dll in the new folder
Run Oxidizer.exe
Run Rust through Steam
If a message box pops up and says "Hooked" then it worked. If it didn't try again.
Enjoy your hacks
You must use an Assembly-CSharp.dll that corresponds with the version of Rust you're using. So basically use RustStripper.
