* Rename enum fields * Naming conventions * Remove unneeded ".this" * Remove unneeded semicolons * Remove unused Usings * Don't use var * Remove unneeded enum underlying types * Explicitly label class visibility * Remove unneeded @ prefixes * Remove unneeded commas * Remove unneeded if expressions * Method doesn't use unsafe code * Remove unneeded casts * Initialized objects don't need an empty constructor * Remove settings from DotSettings * Revert "Explicitly label class visibility" This reverts commit ad5eb5787cc5b27a4631cd46ef5f551c4ae95e51. * Small changes * Revert external enum renaming * Changes from feedback * Apply previous refactorings to the merged code
