How to edit the MSIL Code?

[Subi]

I need to do some small typo alteration of my code in client desktop, I came to know that we can open the MSIL code and do those minor changes.

Can anyone help me to find a way to edit the code without affecting the overall performance, because we are not compiling it after that

I don't recommend doing it, but here is an answer from the MS forums:
