Hey there, I'm new here and barely starting to write in C# :) I followed the tutorial in here to create the 2D game but the cannon does not shows after I followed the tutorial but when i opened the code the cannon was working perfectly and rotating... I was wondering if this means I did something wrong or that XNA 3.0 is different from 2.0? I'm kind of worried :| because I bought a book through ebay (i still wating for it) but is for XNA 2.0 I thought there was no difference thats why i bought it. Anyways, my question is, is XNA 2.0 different from 3.0 (in the programming part)?? Thank you ^^

Of course there's differences between 2.0 and 3.0. They wouldn't release a new version if there weren't changes. In visual studio, hit F1. Go to XNA Game Studio and look for "What's New In This Release." That'll list all the changes.

I see...so my book will be useless? would I be able to at least learn the basics?

It won't be useless, as the setup of the templates and the way projects are built has not changed significantly. There are changes to some of the functions, which can be found in the "What's New" section as mentioned. 3.0 introduced a lot of new functionality, but not having a book targeting that information isn't a problem. The basics you pick up from a 2.0 book will still very much apply.

On that note, you'd do well to spend some time learning C# itself. Diving into game programming without knowing the programming language, or indeed with no programming experience, can be really discouraging. There's lots of good advice in these forums with how to proceed, but you'll probably want to start by learning C# and then start looking at XNA.

A really good list of books and websites can be found in this post.

Not at all. The changes are usually in relation to adding new features in XNA so your old code should run fine (I've upgraded a few projects from 2.0 to 3.0 without having to touch any source (or if I did it must have been minor because I can't remember)). If there are changes that should break your code (and I'm sure no library/framework programmer would do this on purpose without a valid reason) then the list of changes in the documentation should have information about it and may suggest an alternative.

Thank you for the links! I will be ordering the beginning learning book for C#

I see ^^ thank you once again. You all are very helpful.
