Wow, there really are people who just drive-by downvote anything that doesn't a-priori agree with their cargo cult mentality instead of stopping to think about it for 30 seconds? Of course they can't leave a comment, because that would require them to actually consider my point, which would put them in danger of actually learning something.

Downvoter, the problem with your downvote is that I am correct. DLL dependency/deployment is a completely separate concern from code contracts and visibility; therefore "internal" is always a mistake and should never have been added to the language. If you use "internal", we've identified that you have gaps in your understanding of software development that you have the opportunity to fill. But instead, go ahead and just downvote me again without comment. That's a lot easier than improving.
