Reformat + Refactor: Used Resharper to clean up the code a bit so that the code is up-to-date for current C# standards.
This was mostly because I was working on the code and it was easier to work with, should have done it after I made all the changes so you can ignore them, but if you want them removed, it isn't too difficult to reproduce the changes without this step.

I also removed the obj folder and added it to the gitignore
