Extra Functions in the Exploit API

why would you ever implement these in .Net these are custom functions for the module they would  need to be implemented by the api owner themselves cause they are expected to interact with roblox and luau to perform the functions, you can view their docs on unc's github aswell as more info.

Implementing functions in a closed source distribution is restricted and not recommended. You can define functions into the lua environment in its env but anything involved with memory access will not be possible. These limitations mean you can only do things inside the Lua environment making the majority of functions impossible with these limitations. The developer is really the only person who can actually add functions. An example of adding functions through a lua environement is scripts like MoreUNC who managed to replicate functions possible to replicate within the lua environment.
