First off, I am a complete novice at this. I consider myself computer savvy, but am new to csharp modding. Anyways, kinda new to the game and have been hooked (to say the least) and my save game editing was only getting me so far Didnt really see anything about getting dnSpy set up for the game and have seen a few questions regarding this so here goes. People who are more knowledgeable about this, please chime in if I butcher anything. 1) Get dnSpy, open your Csharp, right click and use the edit method option. 2) On the bottom left hand of the screen (red circle) click 'Add Assembly Reference' 3) From the open dialogue screen, navigate to your ...steamapps\common\Motorsport Manager\MM_Data\Managed folder and i select everything in the folder except for the 4 files that begin with "assembly" and open em all. Note: there are specific ones that you can open, you dont need em all, I got lazy trying to isolate which ones I needed exactly and just selecting em all but the 4 seems to work ok. Too lazy to update pic, but those two Assembly first pass DLL's are needed as well You should no longer get any more of the pesky compile errors. As I said, I am a novice at this so if you have any questions I prolly cant help, haha. Anyways, seems pretty straight forward, and so far works good for me in my tests.
