I'm currently reverse-engineering my own DLL because I somehow managed to lose its source code. Somehow I never committed it anywhere and wherever its copy was I deleted because I thought it wasn't important.
That is why, even for the smallest project and even if I don't need to share the code with others, I always create a local Git repo as the first step. In the most simple case, you don't even have to push it to a server.
Also, I bought a Zotac ZBox as my "server" to run a Gitea instance and I mirror all my code there, just in case: https://gitea.io/en-us/
I do! This is a repository going back seven years and I have it in three separate servers: at work, at home, and on Github. I didn't commit this particular change anywhere. I have literally no idea how this happened.
Was this a native DLL or a .NET DLL? Just curious, since I assume a .NET DLL is a lot easier to reverse engineer. I learned about Ghidra probably like a year or two ago but still haven't bothered using it. I really should, so thanks for the reminder.
