In fact, they even introduced two new developer programs for Windows Phone developers. First, Nokia Ad Exchange (NAX)Â free way for developers to quickly and easily monetise their apps using in-app advertising. Second,Â Nokia Premium Developer Program (NPDP) whichÂ costs $99 USD for an annual membership, and this membership gives you tools and services valued at up to $1,500 USD.
Now, Nokia has published a guide with hundreds of pages about the new features that are part.
