Hello everyone! I am patching a file by DnSPY, so here is what I did:

1. Open file with DnSpy

2. Search for the function I want to patch

3. Patch the function by changing the first IL opcode to "ret"

4. Enable the "Keep old maxstack" checkbox

5. Save the new file

But the problem is that, this software usually has a new update, and everytime it updates, I have to re-patch again which is time-consuming. So do you guys know any library/method that can help me automate this process? Any help will be appreciated.

You could give it a try to some .net patching library, eg Harmony (there are more)
