I have been running into a very strange problem with my SetUsername RPC. It is a server-side RPC, so it has to run an implementation of the function, but when I add _Implementation to the end of SetUsername in the .cpp file, it causes a compiler error because Visual Studio does not recognize it as a definition. I have looked everywhere for a solution, but I have not found any information on this problem. I have included screenshots of both files with the function and errors visible. Any input is appreciated.
