Daniel Fernandez with his usual genius has created a great application that you can download from
http://www.codeplex.com/addonstudio that allows you to work with WOW, but use the Visual Studio shell. This is a great way to get into programming and to have fun.
If you are a teacher that wants to get students interested in technology, and you can get access to World of Warcraft, this might be the way. If you are a teacher that expects students to all have the same experience, than WoW is expensive and not all students will have access.
If you are a hobbyist, this is a great way to go and to have fun, if you like these types of games. I am having problems with the screen size, but that can be resolved.
So load it up and get started!
