> This code should work as is using Mono.

Sure, this one does, but nearly any .NET program with a GUI won't. It's very frustrating to run into useful programs that I can't run, and most often applications that fit that description are written in a .NET language.

Yeah, true. There's nothing hard about reading C#, just running it.

You make it sound as if there were no portable (or 'non-windows') C# applications. Stuff I care about:

At least in the game-hacking-with-a-GUI space, there very nearly aren't any.

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.
