I've added a prebuilt Windows release for convenience.
You will need .NET framework 4.6.1 installed (most windows computers already have it)
You can use a python script like the following to overwrite-in-place the files:
from pathlib import Path
import subprocess
directory_to_process = 'C:/temp/hou_steam/fixed'
exe = 'C:/temp/New folder (59)/reorder-attributes-v1.0.0/ReorderAttributes.exe'
for path in Path(directory_to_process).rglob("*.cs"):
print(f"Processing {path}...")
subprocess.check_call([exe, '-x', path])
