Wow, you're really narrowing this down now. OK, there aren't many tools in the portable C# game-hacking-with-a-GUI space. Why is that such a great issue, and why is it relevant to this article?
It's just annoying, as someone who likes to dabble in that space. There's a lot of good, interesting work done and it's frustrating that it's done using a proprietary technology I can't use when there are tons of other options.
This article is about game hacking using C# and never addressed the issue of portability, because game hackers who use C# never think about portability. That was my point.
Maybe it doesn't address the "issue" of portability because it in fact is a portable program. Maybe it doesn't address portability because it's an article about reverse engineering a game. Maybe it doesn't address portability because the code is meant to illustrate his process rather than for others to port it. I still don't see how your criticism is relevant at all.
