I've posted on Steam discussion and reddit hopefully I'll get some help here. As title states trying to update old mod to latest alpha. I've downloaded several programs I believe are required. I have DnSpy, DMT Tools, Visual Studio, and Unity. So far I've decompiled the mods.dll file using DnSpy into C#. I know the mod I'm working on used Unity 5. From my understanding the process is: 1) decompile the mods.dll file using DnSpy. -Finished. 2) Save decompiled files to C#. -Finished. 3) What is the next step in this process? I assume I need to start a new project using Visual Studio but even after I create the project I don't know how to go about updating/editing/debugging the C# files. Final step is use DMT to compile corrected C# files back into a mods.dll file format. Any help would be greatly appreciated. I really enjoy the challenge of all this and would like to learn more about modding and programing. TIA
