I second the recommendation of the Igor naming guide. Stay away from meaningless strings of alternating vowels and consonants: altana, obito, temora, even if it seems easy and the domains are readily available. Pick something with soul and meaning. Best example: "Plan B" (also known as the morning-after pill). |
@Sam I know this question was about Windows Forms, but you should definitely start looking at WPF. This sort of scenario is *really* easy in WPF with DataTemplates and TemplateSelectors. |
how about you use drupal but scale down and code it according to your needs.

How well does WPF blend with XNA in real life? |

I understand that there are several ways to blend XNA and WPF within the same application. I find it enticing to use WPF for all GUI and HUD stuff in my XNA games.

I think that you're consistent is more important than what conventions you go with. As far as future-proofing yourself, that's a matter of the code that you're making a framework for. It's a lot easier to build on a brick house than a sand one. |
You are going to be fighting a loosing battle if you try to obfuscate your code in the hopes of someone not stealing it. You may stop the casual browser getting at it, but someone dedicated would almost certinly be able to overcome any measure you use.

Further, the call stack must typically be recorded at the time of the exception being _thrown_; once it has been _caught_ the stack has unrolled, so you no longer know what was going on at the point of being thrown.

Yeah there is nothing different about throwing exceptions in using blocks.
Remember that the using block basically translates to:

If it's a setter method and null is being passed to it, I think it would make more sense to throw an IllegalArgumentException. A NullPointerException seems to make more sense in the case where you're attempting to actually use the null.
