I've modified the source code for a .dll, but I'm not sure how to recompile it. I just opened one of the source code .cs files with Notepad and made a few changes. I think if I can load it in Visual Studio properly, I could probably figure out how to export it as a .dll, but I don't know how to load the altered files in the first place. Is there some way I could edit a dll in Visual Studio directly?
