1. I am a WOW Addon programming beginner , i was confused by how to start my first addon programming. is there some tutorial which can show me how to make a simple addon step by step ? include the envirment, code editor, how to build and debug your code.

    since i found that there is a tool named WOW Addon studio which looks like visual studio, does this tool still active now or are there some other tools now?

    These forums are for the support of the book, which you can use to get all of this information. I do not provide free tutorials.
